Hi 

In Harward universtiy ,it is extremely hard to selective .selective percentage is only 6% .

Meeting their GPA requirements SAT/ACT requirement is very important to getting past their first round of filters and proving your academic preparation .

SAT/ACT is very hard in competitive .you need to do well to have a strong application .

And your Academic side also should be very strong including your GPA scores ..etc ..

Only strong application candidate will have a chance of getting selected.

Thanks
