Dear Aspirant,

First of all, the mock tests are usually set harder than the actual exam so we can easily assume a +- 5 percentage in the actual exam.

The scope of improvement in your performance depends on how much you have prepared till now.

1. Analyze your performance thoroughly

Look at where you are losing marks. Look at what concepts you are weak in. Try and revise those concepts again. If you are making some careless mistakes try and pay more attention to each question before answering them.

2. Come up with a strategy

Performance in exams are usually about how well you can strategize. Don't try to attempt a lot of questions. Try and learn to pick easy questions quickly. Focus on your strength. Make sure you attempt enough to clear the cutoff in each subject as well.

3. Make good revision notes

When you are making revisions notes, you'll be able to get a clearer picture in your own mind and then you'll be able to see where you are lacking. This will also help you on the days before exams.

4. Solve previous year question papers thoroughly

5. Don't try to learn extremely difficult concepts now. Focus on concepts like statistics, inorganic chemistry so that you can score better with least effort.
