Hello candidate,

Exams such as INTSO, GTSO, ATSO and others are National level Olympiad examinations consisting of subjects such as Mathematics, Science, English General knowledge and others held throughout the nation.

Several coaching institutes offer classes in order to crack such Olympiad examinations, and the student can also practice sample papers and attempt mock test in order to to get a better preparation for such exams. The main thing which we should keep in mind while preparing for his exams is continuous revision and regular self study.

Have a Good Day.
