    • With daily practice, you can improve your accuracy level.
    • After getting the accuracy you much start working on your speed of attempting the questions.
    • In any case, you are not able to maintain a good speed then you must focus on accuracy only.
    • You can attempt mock tests as they are like real exams and will help you in getting more clarity about your accuracy level and speed.

    4. Attend Video Lectures

    • Some time candidates can afford coaching classes. In that case, you can go for free videos on Youtube.
    • You can attend free lectures related to your topics. 
    • These lectures will help you to clear the doubts if any.

    5. Revision is Must

    • Candidates are advised not to leave any topic for the end days. 
    • You must save the last 2 weeks for revisions only.
    • Regular revisions are also important as they help you in memorizing things.
    • Do not compare your preparations with your friends. Stick to your plan only
