students can improve their math performance by putting forth additional effect when necessary.

Question

True or false

I think it's True correct me if I'm wrong

Answer 1

effort? effect makes no sense.

Usually true. One could better specify what "improved performance" means, and I would be happier. improved performance is NOT better grades, usually.

Answer 2

If you mean effort then you are right.

Maybe some of that effort should go into spelling, typing, or proofreading...
