Hello Subham!

Hard times arrive at any kind of situation. But it should not limit you from achieving success. Please don't get disheartened due to the low percentage on the 12th. You will eventually realize that it doesn't matter.

Career options in the engineering and medical field may prove tough for you to get admission. But there are so many good career options left.

You may get into several Arts- specific degrees and also in things like Media including Journalism. Similarly you can pursue Diplomas in Computer Languages, Animation, Films etc. With that bachelor degree earned, you can easily get into some masters and remove the humiliation of relatively low marks in school.

Later in life you may become very successful. Remember that some IAS officers had very less percentage in their school but nobody cares about that when they become successful.

When there is will there is way.

All the best!
