Right now I am in 10 standred. What I can see is right now at my this age that I might be able to make it to IITβs Earlier I thought I am gonna take SAT and go abroad but I kicked that idea cus someone has said this βApne desh mein etna hai bahar jane ki kya jarruratβ also my friend Dylan Matlin From america Advised me that not to take SAT he already gave SAT SAT is a scam xD.
~based on true story
Donβt you think more than anyone telling you about how is the subject, what is the best subject you can take, you should rather find the subject in which you find your interest.
Trust me (based on bunch of true stories) the thing in which you found interest you will do much better than anyone else.
Nobody can tell you what is the right one for you its only you yourself will knew it.
And btw interest means even if u that thing for hours you will not feel bored and continue doing it.
