Hi!
Guys I’m international student. I have a perfect score in Sat, sat subject tests/world history, M1, M2/.
But I don’t have many awards. Very few. My GPA is 3.7
So am I strong enough to get into Harvard?
We need to know more about you to give you a better “chance.” What about ECs?
How did you manage to get a perfect score on the SAT with the grammar you’ve displayed on these forums?
Followup: You are misleading your readers. In other posts in the past few days, you posts make it clear you have not yet taken these tests. Odds are you will not be able to get perfect scores, so there is no point in chancing you. After you take the tests and get your results, come back and ask again with your real scores, as well as a lot more detail on your qualifications, as SAT scores will only be a small part of your application.
Actually it was my sister. Not me 
Then your sister needs to get her own ID and account. Closing thread.
