Hello tarun
If you have failed in one subject , you need not to worry .Just tighten your belts and apply for the compartment exam which will be held in july or august .Just work hard for it and pass it with a minimum of 45% marks .If in least cases , you can't even make upto it , then only you will be considered as fail (only in your marksheet , not in your life)
Don't lose hope .
Best regards
