Scaling of your subjects are okay except General Mathematics and Business Studies. Your ranks are actually fine, however, considering your school rank...you will be most likely pulled down by your peers if you want UAI anything above 80.
My educated guess is that you will get around high 60 if not low 70 with your current ranks.
You will have to really lift up your game in your lowly ranked subjects such as legal and business.
