What should I do if I fail class11

Class 11th and 12th have a lot of importance in your life and form the foundation over which you would be building up your future career.

Class 11th specially deals with the basics and having a strong hold on class 11th topics does give you a strong foundation to appear in many competitive exams in future.

As you know failure is a part of our life and it's nothing to be afraid of. I would suggest you do your class 11th once more with full dedication and pass the exam with good score. Learn from your mistakes and most importantly never give up, just keep moving forward.

Best of luck my friend.
