Hi Amar!

If you are confident that you can score upto 85-90% in 12th boards then it will be quite easier for you to prepare for the KCET in 1 month and possibly achieve the rank below 1000.

>> First of all, get familiar with the syllabus, try to cut out the extra topics and do not wate time on them.

>> Then, learn the fundamentals/basics. You can start by NCERT Textbooks.

>> Once you have completed the syllabus, try to solve some previous year question papers (as you are writing the paper actually). Check out the weak topics and try to improve them later.

>> If you can score 45+ easily in each subject, try to reach to the 60 in each subject, it will help to improve your confidence.

>> Lastly, keep revising and stay calm.

Thankyou!
