Is an ACT score of 20 good?

It really does depend on what school you are aiming to go to. I THINK it is good, at worst it is about average. Like I said, it is important to compare your scores to those that pple in the college you want to go to have made.

20 is out of remedial stuff at most schools. They may require a 19 on the sub-test for the subject not just a 20 composite. Most scholarships at public universities start at a 24, will full tuition starting at 27 or 28.

It might depend on where you live. In TN, you can have 21 and get into any college here...In other states it might be higher or lower. I'd just check it out and see...If you arent satisfied, I'd take it again.

I believe that is around average, if not slightly above.

When I was applying for college, 20 was borderlining the lowest you could get and still expect to get into college. Bear in mind, this was for schools that required ACT scores. Not all schools require it. You really need to ask the people in the Admissions Office at the school you are applying you. They can tell you whether or not you need the ACT and how high they expect ACT scores to be. Many have a minimum requirement of 24. My other suggestion is to take the test again and give schools the higher of the two, OR send in both tests that have scoring from all four tests you took (Reading, Verbal, Math, and Science) and some schools will take the higher scores and come up with a new composite score for you. For Example:

Test A.
Math--18
Reading--25
Science--21
Verbal/Vocab.--26
Composite--23

Test B.
Math--21
Reading--28
Science--25
Vocab--22
Composite--24

Combination:
Math--21
Reading--28
Science--25
Vocab--26
Composite--25

Bear in mind, I'm throwing out numbers here, but you get my point. One other thing I would add is that if you get a chance to take the test again, PACE YOURSELF. It's a long test and it turns your brains into scrambled eggs, but it's worth it once it's all over.

One last thing: If anyone pulls the fire alarm during the test like they did during mine, you have my permission to smack them. ;) Good luck! I hope this helps! :)
