Thank youuuu. This is so helpful.

Good video, in India mostly people solve IE Irodov and Krotov with previous year questions and do Resnick Halliday and Krane for theory. ( For Indian Physics Olympiad)

Isn’t Chemistry Principles: The Quest For Insight, the Chemistry book that people use? Not Physical Chemistry. I have both but idk which one to use.

@Cararra

4 жыл бұрын

Hmm i looked at the difference, and from what I can see the physical chemistry is a lot more in depth (but the other one covers all of the necessary concepts too). I can't say which is better, but the physical chemistry one might be good if you want a more in-depth/advanced view.

so cararra on a scale of 1-10 how hard will the open exam be if I took AP Bio and read the Campell book once (btw I will definitely do more studying then that)

@Cararra

3 жыл бұрын

I think it'll be pretty hard, but I'm going to be completely honest it wasn't easy for me even after reading Campbell over and over again. You for sure can pass but I don't think reading Campbell once will give you much of a margin.

For f=ma, after reading the textbooks, are there any "f=ma" type problems that are NOT past tests? I don't want to waste the tests.

I'm gonna be honest, you really can't (although if you only have two weeks you should probably focus on cramming vocab and hope you remember the basic concepts) I don't know the distribution for your finals but USABO has a lot more focus on animal/plant physiology + genetics so maybe focus on those chapters, but I wouldn't call that studying the book since thats a fairly small subset

www.famat.org/PublicPages/TestArchive.aspx?qy=true&category=&host=&level=Calculus&style=(Individual)&year=&calc= is an excellent resource (Mu alpha theta competitions from Florida). The calc problems are more difficult than anything you would need on USAPhO (most of them).

@Cararra

For calc, any hs calc textbook works (my school uses Stewart's), it will probs take around 2 months if you focus. Getting faster at problems is just a matter of doing a ton of problems, I'm not sure there's any other way

This might be a bit late but basically it’s this series of STEM test competition, where if you score good (above the cutoff) then you get to advance to the next test. There are different tests for different subject such as math, physics, bio and all that. The problems are pretty challenging and it will just get harder as you advance farther.

They're decently helpful if u're just starting out but they aren't as helpful once you're in silver. I think past exam problems are your best bet, but if u need more USACO Guide is really good.

I wouldn't recommend using them purely for high school courses, but if you do olympiads, courses become way easier in general

I am a sophomore currently and I want to do USACO and USNCO. for usaco, I am decent with java as I can solve almost all of the bronze ones, and I am planning attend the december one to hopefully make silver(yes ik java is bad for usaco, but I know 0 c++) My overall goal at the end of high school is to reach platinum (im fine with gold also). for usnco, I am currently taking Ap chemistry, but I am not that great at chem. I took a local practice test on my own and I got like a 31/60 on it, and I want to qualify to the national exam by this march. my overall goal at the end of high school for usnco is to place well at nats (top 200 or better). Do you think I can accomplish my goal if i spend like 10 hours a week preparing for both of these simultaneously? Thanks

Start with Morin red book then F=ma practice tests, once you pass to USAPhO go through HRK volumes 1 and 2 and grind tf out of physics, then past USAPhO exams for practice to get gold or camp. If you can’t understand Morin red, start with Morin blue, if you can’t understand Morin blue then start with AP Physics C, if you can’t understand that then idk don’t do usapho lol (but I think if you’re interested in usapho then you should already be getting a 5 in both AP Physics Cs lol)
