Hi there,  if you want to qualify national standard examination NSE you have to focus and basically the science subjects and you have to also focus the same for JEE mains and BITSAT basically focus on NCERT syllabus syllabus previous year questions to qualify JEE mains and BITSAT. Focus on the chapter specially gravitation for the NSE Olympiad . Do the previous year papers of the Olympiad and ask your teachers and collaborate with them . Hope this will help you .
