How to get an A- in two weeks?

Ok So in Math I ahve a 88.84 percent. And i need to raise it in two weeks before grade cut off.

All I can do is quizzes -25 points

Tests- 100 points

and Portfolios- 50 points

There is not a lot of ways to improve it but im up to any suggestions. Also he gives no extra credits.

I took a quiz today i think i missed 2 so i think i got a 19/25

what would my grade change to?

PLEASE HELP!

study really hard and you have to get grades higher than a 90% so your grade will raise up to a 90%. if you could get 95's on your assignments, that should raise your grade up to an A-
