Is EGMO overkill for late amc - mid-late aime geo?
I'm working through chapters 2 and 3 right now and was just wondering if it would be useful to continue with the book given the level i'm at

i can mock ~130-138 on amc 10s, but how do i mock 141+ for lighter jmo qual

Say you take the USAMTS and AMC10, and you qualify for AIME through both pathways.

Does your JMO qualification now depend on your AMC10 pathway (AMC + AIME), or just the 9+ on AIME required for JMO Qual through the USAMTS + AIME pathway?

Are you even allowed to take both USAMTS and AMC10 in the first place?

Is OTIS or WOOT better? I know OTIS is self-paced, and I'm a little worried that I won't be able to do as much as work because I have a lot of other stuff going on in my life during the school year. WOOT, on the other hand, has weekly homework, which makes me have to do it. I can spend at least 20 hours a week on this, and at least 10 hours during competition season. Can you please give me your honest opinion on this? Thanks :yup:

(I meant to say amc 10 preparation, my bad)

I need help. I was recently doing some math but thought that this math tool was really unproductive to me, so I switched to other math tools, until I was like, “ok, is there any math tool that is even remotely good?” So now I’m asking you guys, what books/websites/tests should I do to prep for AIME? (Note: when doing mock tests, I got an average of around 100, not sure if that’s good because I’m pretty sure there’s no aime cutoff announcement in google rn for earlier tests)
Also im making this post before I search for any posts that already do this, so please don’t say anything like there’s already a post for that. Thank you guys!!!

Hello orz aopers
What are your thoughts on vol 1 compared to reading intro alg, into c&p, and intro geo for amc10/12 prep?
I've heard many varying opinions on this some saying that vol 1 doesnt cover enough depth.

Hello, I am a math enthusiast comfortable with algebra and basic calculus and wish to begin physics. Though many sources would recommend HRK, I do not learn well whatsoever with text books. Does anybody have a full online crash course to get a student to USAPhO qualification level within 6 to 9 months? Thank You.
