HELP PLZ

So I am a jee aspirant (class 12th) and I will give jee mains april attempt but my cousin which is a neet dropper will also give this attempt and he is very good in studies so I thought that he can score more than me in the 2nd attempt and my parents are not so educated so they will think that me who prepared only for jee can't score more than the guy who prepared for neet only. Now what I can do ( apart from studies)
