Question about GPA

Okay, so I’m in 8th grade taking 3 high school credit courses which they say factors into my GPA. This is what I got for the 1st semester for each class:

Algebra: 81
Art: 92
Spanish: 97

and now for the 2nd semester, which I only have one grade but I estimate the 2nd semester grades are gonna be these:

Algebra: 92
Art: 94
Spanish: 97

Are these bad grades?? I’m worried about the 1st semester!!!

By the way, when I start high school, what grades should I aim for?

You should forget about college right now and enjoy your middle and high school. Then you should master the material at the highest level possible and not focus on grades. Grades and mastery are different concepts. if you mast the material at the highest level possible I’m sure your grades will reflect that. But don’t spend years grubbing for grades.
