Pick the common part of the syllabus - The syllabus of most competitive exams is based on the Board Syllabus. Hence, go through the syllabus of every subject in both examinations and make a list of topics that are common to both. Your primary focus should be to finish these common topics off.
Pick a challenging topic from the remaining syllabus - By now, if you revised everything well, you must have revised almost 90 percent of the syllabus. But there is a chance that some topics were too hard to revise with the other topics.
The next step is the mock test - Mock test preparation is a must for any competitive and board exams. Sample papers are available on the internet free of cost. Download those PDFs and start your preparation from today itself.
Solve Mock Test Paper - Solve as much mock test paper you can solve in a day. If you are well-versed with all concepts then you will score good marks in the mock test.
Correlate the topic - There is always a relation of topics between board exams and competitive exams. Hence, what similar topics will be asked in both, prepare them first.
Finish off the entire syllabus - If time allows, finish off the entire syllabus and get yourself completely ready for the exams. If you go to the examination hall knowing that you’ve revised everything well, you’ll be in a better mindset to attempt the exam.
Stay calm and stress-free - Always staying in tension will not give you the desired outcome. Always be cool-minded and do not worry about ifs and buts. Just stay confident in what you have prepared and be positive. One exam does not decide your destiny.
