am a student of askiitians also.. and sir/maam please guide me on the international math and science olypiads ,what are the portions and when will it be conducted. and which books need to be referred. thanks!

Olympiads are for students who have not yet passed.

The first round is regional level in which you qualify for a national round . around 50 students are selected from that who visit the camp and

among them few students are selected on performance basis for international round.

Truly speaking , as the director of one who conducted the camp few years back told me that NCERT book was enough for physics olympiad.

However, from the experience of people who have qualified , the recommended boos are resnik halliday and irodov.

For chemistry , morrson boyd,jd lee, atkins and NCERT.

And for math follow challenges and thrills in pre -colleges in mathematics.

The exams are generally conducted in nov-dec .It is conducted by IAPT,IACT.
