0:01 Hello everyone. I hope you all are doing well. First of all, sorry for the delay in this video. Uh for the past few days, my health was not in a good condition. I was not even able to speak for the past 2 or 3 days. But currently my situation has improved and I think now uh I can make a new video. Now in this video I will focus about my physics, chemistry and mathematics preparation for IIT exam biotechnology exam. Not only for this exam uh apart from the IIT exam in GATE biotechnology, GATE BT uh GATB in this exams there are a portion uh for physics, chemistry and
0:46 mathematics. Uh and this is very important for you to prepare for these three subject also otherwise your marks will be average and you will be able to qualify the exam but that won't be enough to secure a good rank in the exam. Therefore, these three subjects are the rank boosters which boost your rank. Biology may be a qualifier subject which will help you to qualify the exam in the mass skill. But uh to secure a good rank you will have you should have a good command on physics, chemistry and mathematics. Now first of all uh uh I will divide the video in two section. uh firstly I will uh focus what what are the major topics to cover for these exams and after that what are the resources from where you should study
1:32 these topics such that uh you can complete the whole syllabus whole physics chemistry and mathematics syllabus of course for the exams not for IG or neat exam for biotechnology IT MBT or GATBY these kind of exams MS entrance exams and what are the resources I will later focus I will focus on that in the later part of this video. Now firstly I will focus on physics. Now for physics for class 12th u you have to focus on electrostatics u electrostatics electric potential electric charge and field uh current electricity uh within the current electricity the major important topics are drift drift velocity mobility combination of resistors and combination
2:19 of batteries. After that uh moving on to the magnetism you only focus on the first part of the magnetism like calculation of magnetic field for different shapes and magnetic field and you should remember the unit of all the magnetic uh properties and they frequently ask question from uh unit of different quantities. Um there might be a left right row matching these kind of questions. Uh from electromagnetic induction or latter part of the magnetism they generally don't ask much more questions but from the first part Bart law amp circuit law these are few important topics. Now for uh ray optics ray optics
3:06 is a very important topic in each exam you will find at least one or two questions from the reoptics. uh you have to learn how to make the images from the distance uh distance from the image and distance from the object. The formulas lens maker formula uh from the horizontal slab parallel slab that formula formula of the prism uh these are few important things and formula telescope you have you don't need to derive all that things you just remember the formula practice one or two questions on the topic and that would be enough now moving on to the wave optics uh you can uh focus on the things like interference of waves constructive and destructive uh interference what will be the resultant amplitude the resultant intensity and these are very
3:52 important uh yong's double double circuit uh experiment double experiment and these are the things now for unit and dimension which is the first first chapter in class 11th uh error calculation from where they frequently ask questions after that uh motion in 1D 2D Newton laws of motion and friction motion in 2D means projectile motion, riverboard problem, rainman problem. Uh you just practice one or two and two type of questions from each topic and that would be enough. And after that rigid body dynamics uh which most students uh used to leave because they think this is the tough I also during class 11th that was a covid time and I have not prepared well
4:38 prepared for this chapter but after after completing HS exam and when I was in college uh I I saw one of lecture and try to cover most part of this chapter because this chapter has a good weightage in all the all these competitive exams you you don't need to complete the whole chapter you should focus discuss on major topics like moment of inertia, conservation of angular momentum, radius of direction and these things are mainly important and after that gravitation from gravitation you just remember the major formulas and that would be gravitational force uh value of g uh the satellite the satellite formulas what would be the speed what would be the radius and that things uh only formula based questions
5:24 they ask from gravitation after that mechanical properties of solid and liquid. These two chapters have has very high weightage in in this MS terms exams and you only need to learn the formulas and and practice one or two MCQs for based on each formula and that would be enough. You don't need to derive anything as I have mentioned but for thermodynamics thermodynamics and kinetic theory of gases they generally many times ask conceptual questions from thermodynamics and kinetic theory of gases. Therefore you should learn these topics in detail specifically thermodynamics and there these in physics and chemistry both contains the thermodynamics. The basic concept uh basic differences concept lies in the work where compression is positive where
6:10 compression is negative. Work done in the on the system is positive work done by the system is positive. Otherwise both parts are both topics are basically the same. But uh you should learn these things like thermodynamics and kinetic theory of gases in detail. After that thermal expansion you just learn one formula like L of alpha beta gamma expansion of length and volume and surface area. These are the major topics in physics. Uh apart from that they generally don't ask so much questions. The topics I have mentioned mentioned now are the major topics and uh I think all the questions would be from these topics. If you have any questions like
6:57 uh what are the major topics to cover uh in each chapter uh I have opened a telegram channel and you can message me there and I will mention the topics and if I have any short note or formula sheet I will also provide that uh in the channel. Now moving to the chemistry part. Uh in class 11 chemistry uh first some basic concept of chemistry. Here you should learn the concept of mole marity normality uh above the number v1 equal to v2. These kind of basic formulas that will be very important and uh there are very much application of this formula like v1 equal to b2 in practicals in interviews and also in the competitive exam. They ask many questions from this formula. Now from
7:42 atomic structure you don't need to cover the whole chapter. You just learn formulas of calculation of ionization enthalpy uh calculation of radius readback equation uh deeply oil calculation. These are the major topics and from periodic table you just learn the trend trends trends of radius electro negativity electron affinity ionization enthalpy the exceptional ionization enthalpy like bium boron um nitrogen oxygen and these are the important things and uh now chemical bonding chemical bonding is very important uh you should learn in detail this chapter specifically valance one theory BPR and molecular orbital theory and the concept of hybridization that is very important uh frequently they ask from hybrid hybridization and they name a particular molecule and what kind of hybridization it
8:29 shows. Uh they generally ask questions like column matching. They will ask they will give you name of two or three molecules and they will mention the name of hybridization sp2 sp3 and you have to match the column. These kind of questions are generally asked. Now from the gas laws uh properties of gases uh you have to learn the major major laws. Boil's law, Charles law, uh Gakard and finally ideal gas equation PV equ= to NR otherwise they generally ask don't ask so much question other question and the most important thing is ionic equilibrium that is very very important uh you have to learn concept of pH pKa buffer strong and weak acid and finally Henderson equation uh and
9:15 also question also practice many many question on these topics because this is very important Not only from the point of view of the exam in the interviews, this is a major topics which is asked frequently. Uh now in organic chemistry for class 11 organic chemistry you can focus on topics like uh UPS nomenclature basic nomenclature and isomeism. After that in the reaction mechanism you should learn SN1, SN2, E1 that that is very important and hydrocarbons specifically the conversion of alken alkine alken alken alkine uh ben ringing reactions and all the name reactions we should specifically focus on that and a griner reagent that is a very important part and each in each paper they generally ask from one
10:01 question at least from the griner reagent. So you you just make a se make a separate seed and name all the reactions and write the reactions what is the reagent and that would be very helpful and frequently revise that because uh organic chemistry is all about revision if you don't revise then you will not be able to remember those things because there are also logic behind each reaction and mechanism of each reaction but if you try to learn all the mechanisms then it will going to take huge amount of time and huge amount of effort. And I think uh that won't be effective because you have to practice more questions rather focus on learning the mechanisms. This is a good thing no doubt but that is for chemistry honor student and if you start to learn
10:46 organic chemistry like the honors um that is not a intelligent choice. And for class 12th organic chemistry alkaline and alihalide that will be a very important part and uh caroxilic acid they generally ask one or two questions from that and specifically alo reaction canal reaction these name reactions are specifically very important the name of the reagent uh used in the reaction and uh what is the pro product and the uh reactant molecules. uh you should learn that and after that in the class 12 solution solution chapter first chapter uh you should learn the concept like marity normality
11:33 the relationship between marity normality ppm uh and collleative properties collleative properties is very important uh you should learn the formulas you just learn the formulas and that would be enough each property and the formula for each property uh that would be enough and next electrochemistry electro chemistry is uh important specifically the calculation of emf they will provide you the reduction potential or oxidation potential and from that you have to calculate the emf of the cell that is very important uh you should practice these kind of MCQs one or two one or two or four and that would be enough you should learn the electrochemical series also that is very helpful and chemical kinetics chemical kinetics is one of the major topics in physical chemistry they generally ask one or two questions from chemical kinetics that is this is a very
12:19 easy chapter But this carries a very high weightage in the exams. You just have to remember the order of the reactions and the formula for each order like general reaction and the calculation of half life. Top that is important and the calculation of half life they generally ask at least one question from the calculation of half life in each each paper. These are the major topics in physics and chemistry. After that in mathematics uh they generally ask three to four questions from mathematics not more than that. And if you practice chapters like matrix and determinant, calculus, a limit and continuity, integration, derivation, uh in in limits a hospital rule they generally ask questions on that and coordination chemistry uh equation different kind of equations like circle,
13:05 parabola, hyperola, straight line and statistics and probability. These are the major topics of mathematics. You should cover that and I think you will get all the mathematics question from these topics. Now these are the major topics which you should cover uh to attempt to attempt at least 90% of the physics, chemistry, mathematics questions uh which are asked in these competitive exams. Now coming to the materials from which you will revise that. During class 11th and 12th, if you have any well-written note uh which you have read many times and now if you open the notebook you will not feel that this is a new thing then you can revise from that note that would be good choice and
13:52 otherwise if you don't have any note uh focus on the one short video lectures now there is a separate series of lectures called mind map series I won't recommend that because they generally mention all the formulas and in the video but this is not a good choice. you go towards uh one short lectures where each of the chapter will be covered in approximately two or three hours and in that video there must be at least few questions on each formula such that you you may learn the application of each formula. Uh if there is only formula and no numerical then that video I don't recommend at all because that is not a good choice. After that during the preparation of biology in the first video uh where I I I have discussed in detail about my biology
14:38 preparation I mentioned that when you revise you should not make a very detailed note because that is going to consume lots of times and you can learn most of the things from the PDF and for important topics you make a handwritten note but for physics chemistry and mathematics I recommend you to make a good note uh and revise from that note from the second time because there are lots of numericals and you have to learn the formula uh by your choice and in your way and if you don't maintain a good note you will forget from which video lecture you learn that topics and the situation will be very bad uh your effort will go in vain and there will be zero net gain. Now therefore for making a good note
15:23 that is going to take lots of time of yourself and therefore you should start your preparation for physics chemistry and mathematics at least 3 to four month I will recommend four to 5 month before the exam otherwise uh if you start one or two month before the exam you will you will try to find any shortcut and sort method to learn all that things and that won't be effective I have faced the problem and that's why I'm telling you that when the exams are uh around 4 to 5 month after from that time you should start preparation for physics, chemistry and mathematics. Now during preparation you should maintain a good notebook uh for MCQs like you can do you can do two things like uh whenever you complete a chapter and watching a one video you are writing all the formulas and important
16:10 concept in the notebook and after that you also complete the MCQs MCQs just after the portion where you you have written all the formulas otherwise you can maintain a separate notebook for the MCQs And you first write the name of the particular chapter and then 10 to 20 MCQs uh which are maybe the previous year questions or other practice questions and highlight the important questions like which are difficult to you because the easy questions are directly formula based and everyone will will be able to solve that question but the difficult one you should remember and therefore highlight the difficult questions with a different color and that that will help you. You can maintain a maintain a single notebook for formula and MCQ or you may you may prefer to make two separate notebook uh
16:57 as your wish. Now this was all about the preparation. Uh I think I have covered all the major topics. Uh I have opened the telegram channel. you can join to this channel and if you have any doubt regarding your preparation you can ask me there and like uh in any chapter uh if you wish to learn wish to know what are the major topics to cover you can ask me there I will provide you the name of the topics which you should focus on and if I have any short note of formula sheet which I had made during my preparation I will provide I will also provide that in the channel therefore you may join the channel and that's all and if you have any questions you can write in the comment section or in the telegram channel. I will try to answer
17:43 that as soon as possible. Now that's all. Carry on uh carry on your preparation. I wish you all the best. Thank you for your patience. This is a long video I know. Uh if you are if you are in the video till the end. Uh this is a great achievement for me. I believe and thank you. Thank you very much.
