Just another math geek like you guys! :)
I've done TMSCA and can get perfect scores on everything except science (lolz) on both the middle school and high school versions. I also have sufficient knowledge necessary to get all the AMC8 and 10s. SAT's and school work stuff are another one of my fortes. If you need any help, feel free to contact me at ericluo04(at)gmail(dot)com.
I do a little bit of editing on aops: only on the solutions that I read from the AMC and AIME solutions that have grammar/coherency errors.
