Hi Ganesh

I guess you want to know how to analyze your errors in the practice test papers and improve them. Well for that, after you solve the paper, check for its answer keys first, solve the incorrect questions again, if you get stuck anywhere go for the solutions. Go subject wise, and check the type of error you are making, which means that the error is conceptual or solving. For numericals, to remove calculation errors, you need to practice a lot. Solve a lot of questions, varying the difficulty level. For the theoritical part, keep revising the concepts on a daily basis, so that you commit less errors. All questions become easy when you know the concept. So focus on that part. Keep practicing and don't lose hope.

I hope this helps. Good luck!!
