Ouch! What da ya think?

Hey dudes and dudets!
Thus far I’m my high school career I have done pretty well. I admit that freshmen year wasn’t so well considering I had 2 B’s. But I turned that around sophomore year by getting straight A’s (4.0 gpa club haha). Just as high school was going all well I found myself transferring to a new school. And boy do I hate this school. Let’s just say the transfer isn’t going so smoothly and have found myself with 3 B’s : AP physics, AP Euro and honors pre calc. I have 4 AP’s and one dual enrollment class…the rest are AP weighted excluding pre-calc. Btw I have a 1520 on my SAT and my extracirriculars are decent I would say-i have a leadership position in my church, I tutor kids at a local elementary school and i’m the group capital at the library I’m volunteering at. What I’m concerned about is how the decline of grades in my junior year seems to Colleges. This is the first year I’m taking mostly AP weighted classes and I’m afraid it seems like I’m struggling in them. So wise people,how do I think colleges such as Cornell and UCLA will look at my situation. Let’s consider I get all A’s in senior year with a heavy course-load. Oh and let’s say I get 5’s on my AP exam.
