Hello, Since the exam is around the corner there is very little we can do now. You cannot just rely on previous questions. But start now since something is better than nothing. First the pattern is you will get 25 marks from - General knowledge, Hindi, English, Aptitude, Science, Math and remaining 75 marks from technical grade questions. So focus on any question bank for the technical grade questions and not just the previous year questions. Don't think about the result and focus on learning today itself and keep in mind that it will help someday.

Best wishes.
