qqp question1: I find many conceptual errors in questions and answer keys for JEE mock-up tests. FIITJEE AITS seem to have lot of conceptual errors in questions and clerical and conceptual errors in answer keys. Is there any mock-up test for JEE advanced without errors in questions and answer keys? question2: I'm preparing for the JEE. I study a lot. At home I can solve questions. But when I am taking the test, I can't solve them there. What's the solution?
