Hey,
If you are in Grade 12 now and you are about to appear in JEE/SRMJEE/VITEEE, you should concentrate on giving mocks and revising all that you have done so far.

If you are a beginner and have time, you should start with NCERTs make your concepts stronger and then you can go for books like HC Verma, A DAS Gupta, RD SHARMA etc. Side-by-side keep giving mocks. Don't wait for the syllabus to finish - try to give a mock every 15 days. This will help you to assess both your speed and direction (in terms of syllabus coverage).

All the best!

Hello Sparsh,First and foremost while preparing for VITEEE, ensure that you know your CBSE/State Board syllabus thoroughly. Nothing out of the syllabus is going to come for the exam. The CBSE/State Board textbooks are very important in the following units: Inorganic Chemistry – The type of questions asked in competitive exams under this part of Chemistry will directly be based off the reactions given in the standard text book. Chapters like s-block, p-block and d-block elements come under this category. Do the exercise questions given at the end of the chapter first. Some of the questions are frequently asked in competitive exams like JEE Mains, BITSAT as well.Coordinate Geometry – The topic is a vast topic and one can go on and on while trying to prepare for it. But with respect to competitive exams, stick to NCERT syllabus for it. It is also useful to practice drawing graphs for various equations as that technique might come in useful in visualizing certain problems that might be too lengthy for solving mathematically.Semiconductor Devices and their applications – The CBSE book for Physics is the primer for this topic. The book pretty much covers everything required in this topic. Some of it might be useful in college courses like Metallurgy. Other reference books that can be termed as best books for VITEEE preparation by many students are: Physics Arihant Series – DC Pandey Books on Mechanics – Part 1, Mechanics – Part 2, Waves and Thermodynamics, Electricity and Magnetism and Optics and Modern Physics.Concepts of Physics (both volumes) by HC Verma.MCQ Question Bank by D Mukherjee. Chemistry Inorganic Chemistry NCERT Text Book.Organic Chemistry Khan Academy Videos. Mathematics Arihant Series – Dr. SK Goyal.Arihant Past Year AIEEE papers.VITEEE Solved Papers and Mock Tests from Arihant.RD Sharma – Objective Mathematics Part 1 and Part 2 (NCERT difficulty). Biology NCERT Text Book.AC Dutta for Botany – Oxford Publication.Pradeep’s Biology Guide. VIT EEE when preparations done with the right mindset can be an easy exam to crack relatively. Hence it is important to stay focused. The admission process for VITEEEis a little tricky too. The admission rate, however, is also not something to be worried about and is easily doable with simple practice and of course, confidence.The same goes for SRM ENTRANCE EXAM Talking about JEE main exam :-1) Best Books For JEE Main Physics :Concepts of Physics Vol-1 by HC Verma: This book contains the theory and questions of the syllabus of class 11 CBSE curriculum. However, the questions of this book are more difficult than those of the NCERT books. You should solve questions from this book after you have solved the questions of the corresponding topic from the NCERT book. concept of physics vol-1: The contents of this book are based on the CBSE class 12 syllabus. You should try solving the questions from this book after you’re done with the corresponding topic from the NCERT books.Understanding Physics for JEE Main Advanced Mechanics part 1 and part 2: For going from the level of qualifying the JEE Main exam to the level of getting a good rank in JEE Main, the DC Pandey series of books might help you a lot. The books on Mechanics by DC Pandey are one of the best books for JEE Main Mechanics.Understanding Physics for JEE Main Advanced Electricity Magnetism by DC Pandey: This book will help you strengthen your concepts of electricity and magnetism, which is a very important topic for the JEE Main Physics question paper.Understanding Physics for JEE Main Advanced Optics Modern Physics by DC Pandey: This book is helpful for you if you want to make your optics and modern physics concepts crystal clear and solve good quality questions on these topics.Understanding Physics for JEE Main Advanced Waves Thermodynamics by DC Pandey: This is a good book for thermodynamics. 2) Best books for JEE main chemistry : NCERT books for Chemistry: Studying NCERT chemistry books for JEE Main is very important. You should not skip doing this at any cost! In fact, the answers to most of the questions on inorganic chemistry asked in the JEE Main can be directly found in the NCERT inorganic chemistry book!A New Pattern Text Book of Physical Chemistry for Competitions by OP Tandon: You should solve questions from this book once you have solved questions of the corresponding topic from the NCERT books. It has a good balance of theory, objective questions, and subjective questions.Concepts Of Physical Chemistry By Dr. P.Bahadur: This book has some difficult questions and is recommended by many top rankers.Inorganic Chemistry For Competitions For IIT JEE By Dr. O.P. Tandon: After you’re done studying inorganic chemistry from the NCERT textbooks, you can study more details on those topics from this book and then solve questions from that topic.Organic Chemistry by Leroy G. Wade: One of the best books for organic chemistry that explain concepts very well.3) Best books for JEE main mathematics : NCERT books for Mathematics: You should solve the questions firstly from these books when you study the concept for the first time.RD Sharma Mathematics for Class 11 and Class 12: These books are very good for building strong fundamentals. You should solve problems from these books after you’re done with the NCERT books.Arihant Differential Calculus: This is a good book for differential calculus.Arihant Integral Calculus: The questions of this book are very good and will help you get a good grasp on the topic.Arihant Algebra: It has good theory and a great collection of problems.Arihant Vector and 3D Geometry: It has a good mix of theory and problems.Arihant Trigonometry: This book has some good problems. You can solve it alongside the RD Sharma books.IIT Mathematics for JEE Main and Advanced by ML Khanna: Solving questions from this book will help you develop strong fundamentals. You can solve questions from this book after you’re done with the RD Sharma books.
