How do I manage to prepare for IIT JEE without coachings?

A deep study on any subject needs a very good hold on basics. NCERT textbooks are the best-recommended source for that. But only NCERT can not serve the purpose of scoring high in JEE. It must be accompanied by reference books (theory or concept building) and practice books. So, for better scores in Mains, you need to follow the 5-Step-preparation strategy. STEP-1: Master NCERT Every year directly from NCERT, several questions appear. Also, NCERT helps you build a strong bed for your prep. STEP-2: Reference books After mastering NCERT, to build your concepts further, refer to a prominent coaching institute material or reference books. DO NOT forget to make your notes. While you take help from reference books, make sure to stick to the lines of JEE syllabus. You can find a few best BOOK suggestions here STEP-3: Practice Only learning concepts is insufficient. To clear mains, you need to learn to apply the concepts to solve objective questions in the given time. So, solve as many questions as possible but track time. You must master time management while you practice. STEP-4: Test Your self After practicing ample questions, it is necessary to test your knowledge. To do this, Practice the previous year's papers and enroll in Online Mock test series. Remember to take these tests as ACTUAL TESTs. Here are a few past year's papers (download link) STEP-5: Revise This is the crucial step. By implementing the above 4 steps, you would have learned, practiced, and tested your selves. But you must keep all of this intact until you attend your exam. So KEEP REVISING with the help of revision notes. Also, make sure to get all your doubts cleared. read less
