How I can score good marks in 12th Gujarat State Board Examination in remaining few months
Go and study, sound strange but that's what's you need to do.Instead of wasting time in think about how and what to do just focus on what you have.Go through entire syllabus and start staying what you have left.Work and weakness and strength and don't leave any topic or any subject.
good luck



Do remember that you should try and set small goals first and then achieve them.
