Regular studies and completing your CBSE Class 11 Syllabus on time wins you half the game. Complete your projects, assignments and practicals on the day they are assigned and get them out of your way.
Start with easier chapters and gradually proceed to topics that you find more difficult. With basics brushed up, you will find that even the most difficult topics will melt down to simpler easier concepts.
For subjects like Mathematics, Physics, and Chemistry, solve at least 5 to 10 questions daily without failure.
At least three months before the exam, your focus should shift to revision of chapters you already know, solving past year question papers and getting your doubts cleared.
Many CBSE board exam questions are directly picked up from NCERT books. So, read them carefully. Also if you are not able to solve some question you can check out NCERT Solutions.
Biology students must practice their diagrams. Flowcharts and cycles can be a good way to learn lengthy processes that might otherwise seem too difficult to learn.
It is often said that there is no better practice than match practice. Solve one CBSE sample question paper each day, preferably from 10 AM to 1 PM, in an environment as close to the one you expect at your examination. After you have solved the paper, mark yourself as per the CBSE marking scheme. Pick a different subject for each of the five/six days. Assess yourself at the end of the week, look at your weak areas and try to rectify them in the weeks to follow.
On the day of exam, do not worry about the chapters you have not covered well. Most chapters do not carry more than 4 to 5 marks in the CBSE question paper. So, you will still be equipped with more than ammunition to hit off those scores!
