How good is upward trend?

Im considering UC’s, which look mostly at 10 and 11th.
If my 10th grade weighted Gpa is a little higher than my 9th (by like 0.2) and my 11th is like 0.2 higher than my 10th, how good is that?

To be honest, I think these huge public schools have too many applications to deal with to notice something that minor.

In addition, UC’s don’t use 9th grade GPA at all.

it is pretty far down the list of admission criteria.

You could use that in your personal interest questions. Talk about how and why your grades are improving each year, the work you’ve put in, the study habits you’ve learned, etc.
