I would like to give a suggestion that's one thing like before moving on to prepare, you should have a clear strategy. You can listen to every different opinions, but then again you have to customize it as for your strengths and weaknesses. Any time we focus on either over-emphasized on the strengths or on the weaknesses, but you have to take both sides and one thing that I faced while preparing for exams that self-doubt comes, it's very natural. But then again you have to do the self-talk and bring back to the focusing on preparing for the examination and not letting that affect your preparation. Amazing.
