Although great, a 36 on ACT math just shows that you're very good at high school math (algebra, geometry, trig).

If you don't have any standardized scores in higher math (i.e. AP Scores from Calc / Physics C or MathII SAT2) you may be at a disadvantage.

If you come from a heavy ACT state (e.g. Iowa), you can probably get away with just an ACT score.

So I have taken the ACT+writing, two SAT subject tests and two normal SAT tests.
I don't want to send any SAT's at all.
Do I have to?

You don't have to send anything. That just makes it faster and easier for them to reject you.

If you don't send everything, there might be references in the material your school sends or in your recommendations.

Well, dear wordworker do I hear a little sarcasm in your words?
So basically UPenn requires me to send everything I have ever taken?

ps.
I am not from the US, so my school doesn't even know I took those tests. I know what my recommenders wrote because they showed it to me. There is nothing that would hurt me.
