i guess for completion's sake (as in, i don't know if anybody cares otherwise) i should mention that i am returning to math after a somewhat lengthy leave (at my age? i had an unconventional education to begin with..); it's possible i need to brush up on my skills again. but i still think...

so is it possible I'm just no good? i don't think this is the case, or i hope not, sincerely- how would i know? how do you know if you're good at math? is an sat score (or something like it) the best way to know? (i'm obviously unhappy with my score.)

sat math, "test-taking abilities," math ability hey all, are there good reasons for scoring low on the sat that do not stem from poor math ability? what do these 'test-taking abilities' consist of and how do they operate? i took a practice test today and i scored in the 580 range. now, i...

Hey! I'm fifteen and have been self-studying physics and math for quite some time now. I'm getting further into Cohen-Tannoudji and, while I do the exercises, I worry about whether or not I'm doing them correctly. I'd like some problem sets with answers-- online or in book format-- that...

Yay! I love this page! I'm fifteen and I've been self-studying physics for a couple of years now. This page helped me know where to start, what to cover and where to go; I'm glad others can benefit from it, too!

How do I specify the position of the wedge? It's moving freely on a horizontal plane; it doesn't seem like there's a way to tell exactly where it is (at least to me).

Homework Statement A wedge of mass M and angle [alpha] slides freely on a horizontal plane. A particle of mass m moves freely on the wedge. Determine the motion of the particle as well as that of the wedge. Note: We are supposed to use the Lagrangian formulation of mechanics to solve this...

No, I actually looked all over the site... I couldn't find them. Sorry D:

No, it was a full 10-section test. :D

Cool! I'm only thirteen :D

I decided to take a practice SAT for the heck of it -- I went to the official Collegeboard website. I scored 700 on the math and 670 on critical reading. Are these good scores? Thanks.

Thanks for everyone's suggestions. I'll definitely be talking to my doctor about meds. Thanks again, bit188

Hello. I am a thirteen year old recently diagnosed with type one bipolar disorder with psychotic features. Thing is, my meds don't always work. I can't deal with the voices when I am sick. My only coping strategy is my iPod. Are there any ways to make them go away? Thank you *so* much.

Oh my God. I found this on another forum: A mathematician and an engineer agreed to take part in a psychological test. They sat on one side of a room and waited not knowing what to expect. A door opened on the other side and a naked woman came in the room and stood on the far side. They were...

I don't know about "techniques," but I've recently started into real analysis -- I find aleph numbers and the concepts of countability and uncountability to be fascinating.
