Why are you in the IB program?
To me it looks like you have jumped ahead too far too quickly. There really are many classes that you are not ready to take, yet. You need to learn what the right pace is for you.
I am not all that worried about the C in AP World History. On the one hand a freshman in high school should not be taking AP classes. If I were the head of education for the world (I’m not, of course), I would probably outlaw any high school freshman taking any AP class, and AP world history is more difficult than some other AP classes. Also, while having an understanding of world history is in general a good idea, it is not going to be all that necessary of a foundation for other classes that you are about to take.
I am more concerned about the C in Algebra II with trig. Algebra and trig are MAJOR cornerstones for a LOT of mathematics that you will be taking in the future. This is stuff that you are going to need to understand very well. This is stuff that you will use over, and over, and over, and over again.
I think that you need to do two things.
One is to stop taking IB program and at least for the immediate future stop taking AP classes. Take classes that you are ready to take. There are a LOT of very good universities in the US. Your freshman year of high school might have made most of the highest ranked 10 or 20 universities very unlikely to happen for your undergraduate education (a small number won’t even care at all about freshman year), but there are still hundreds and hundreds of very good universities and colleges left to be realistic options. You do not need IB classes and you do not need to take AP classes in your first two years of high school to attend a very good university.
My second advice is that you need to find a way to move forward in mathematics that somehow allows you to compensate for the fact that your foundation in algebra is shaky. Algebra II as a freshman in high school is way, way ahead of normal, but this is also a class that when you take it is something worth learning very well. You probably should talk to your math teacher and figure out what to do about this. This might include some work over the summer. You need to make sure that you are solid on everything that should have come before algebra II.
Finally, I would not worry about ECs. If there is an EC that you want to do then fine, do it. However, ECs are really only important for a tiny handful of the very most selective universities, and you do not need to worry about any of them at this point. ECs should be something that you do for fun, and not something that you do to prepare for any possible university application.
