Any advice would be helpful!

<p>Hi! I'm in a dilemma right now with my class schedule for my sophomore year.
Next year I will be taking 7 classes: </p>

<p>AP Euro,
AP Physics B,
Adv. English 10,
Spanish 2,
Leadership (ASB),
Tennis,
Pre-calculus. </p>

<p>My school doesn't offer much AP/Honors classes. I noticed that there is a chance that I will lose my #1 class rank next year because even if I get straight A's, I will have like a 4.29 GPA. But I'm pretty sure there will be kids taking only 6 classes with 2 weighted classes or maybe even 3 (unlikely). They will have a GPA of 4.33+ . What should I do? I really do not want to drop any of my classes... Our school is also having the IB program, and my class if the first year to participate in it. So I will be on an IB schedule Junior and Senior year. Also, if you have any information on IB, I'd really appreciate it! Like how does it get weighted onto your GPA?</p>
