Hello Manigandarajan,
This is one of the frequently asked questions and you can search the forums for ideas on what other people have done.
Your scores are influenced by a lot of internal and external factors. For example:
1. Are you done with the complete preparation to take full length mock tests?
2. Are you able to finish all questions within time?
3. Are you getting low scores in one area which can impact the overall score?
4. Are you taking the exam around the same time of the day when you feel you is the best?
It is very important to analyze the results to learn where you need to spend the most time revising.
You can refer this

which guides you through the types of questions in the exam, providing tips and recommendations for each of them.
Hope this helps!!
