Is a 4.35/5.0 gpa very good for a 10th grader?

-Most schools use a 4.0 scale, with the 4.0 - 5.0 coming from Honors/AP classes. In that system, a 4.0 means you got an A in every class & the extra points are assigned for college level classes.

In that case, your 4.35 is very good. Congratulations!I'd say so. It's a little better than average so community colleges definitely shouldn't be in your future.
Yes that is really good. Congratulations on working hard and keep up the good work. :)
