being an international student, I am applying.i have average grades in all subjects except maths and physics, i got 97 in 10th and 92 in 12th in maths. I have make many things like thief alarm, electric board game , tesla coil etc . i am developing fomulas in integrals related to inverse by self . in sat i gave only sat 1 not subject test dated due to inavability of my passport that time . i get apprx full in sat maths section but in english i get only 650 . i am higly motivated for maths and physics. does i get any chances to get admitted in MIT or harvard or any Ivy league with financial aid?
Its not likely. Especially if you need financial aid. The international applicant pool is very competitive.
is there is any chances of getting admitted at any other good universities ?
What is your definition of “good universities”?
Google Jeff Levy College Counselor
When you find his website, click on resources then “FA - international students”
It will take you to a list of schools with financial aid for international students.
Unless you are in the top 1% in your country MIT or the Ivy League (note that is an athletic conference) are not realistic. Even if you are in the top 1% it is still a long shot. Based on your statement that your grades are “average” and you had a 92 in 10th and 97 in 12th grade math (I am assuming your left 11th grade out because it wasn’t as good), I think you need to think more realistically.
i forget to mention that have cleared IIT-JEE also for IITs, NITS, here i got 97 percentile apprx
and i give maths and physics tution
and i am class monitor and representative in 9th ,10th
is this increase my chances ?

Nah, as mentioned above, international pool is very very competitive. You need to essentially be the top applicant from your country to even have a chance at top schools. Great grades (yours are average) and great Testing scores (Yours are decent, but average for everyone applying) are like baseline. I’d still encourage you to apply, but don’t be hoping for too much 
Keep it realistic
