Can a weak student crack UPSC CSE?

To answer this question, I would like to begin with a quote “Being weak is a choice, so is being strong”, so this is just your mindset that you are weak.
Especially when it comes to UPSC CSE you cannot judge any person based on his/her scores or ranks in their graduation because UPSC Civil Services Exam is a level playing field for “any person who is a graduate”, that is the only eligibility which is required to appear for this prestigious examination.
