The correct word in the sentence is effect.
Here's why:
- Affect is usually a verb, meaning "to influence or change something."
- Effect is typically a noun, referring to the result of an influence or change.
In this case, tutoring is causing a change (improvement, we hope!) in your grades, so "effect" (the result) is the better fit.
Here's the sentence with the correct word:
I believe that tutoring will have a positive effect on my grades.
