What should I do for a bright future? I got 51% in science and I am really confused.

Don't go for engineering, do B.Sc or B.Com graduation and go for civil services, that will be best for you. Everybody is trying to get admission for engineering.

Hello, If your PCM aggregation is above 50 percent, you will get admission in engineering colleges and if below that, you can get admission in commerce colleges. Thank you. All the best for your future.
