taking 3 summer courses to boost gpa?

i’m taking 3 easy classes this summer. if i get A’s my gpa will be boosted from 3.2 to 3.3
will uc’s mind this and see it as gpa manipulation or is 3 a decent amount? (i know some people take 4 or 5 and then it’s obvious)
the classes are stats, computing, and psychology btw. stats and computing are a bit useful for my major, psych isn’t.
