i get all the hard ones right, i guess the so-called "advanced topics", but i get all the common sense ones, the you-either-know-it-or-you-don't ones wrong. I'm having some real trouble with that.
if anybody could spew out some random facts that they found were asked or found to be useful, that would be great.
for example, i didnt know that CO2 dissolved in water at room temp...i thought it had to be in high P. It is also less dense than air at a given temp and pressure.

Hard water has calcium ions in it.

It's all kind of about applying the definite info that you know to those type of problems. For example, I took the 2 exam without having learned anything about pigments or colors spreading etc, but I used my other knowledge from physics, math, common sense to analytically figure it out. Another HUGE thing is confidence. I can't stress it enough. One big hangup for me was the same thing as yours: that I was expected to know these trivial facts. Then I got on the Olympiad team (out of about 900 nationally) and realized that if I didn't know it, it was likely that maximum only a few people in the state did. That gave me a whole bunch of confidence. By the way, I'm not boasting or anything, I'm just trying to show how the mentality really plays a part in it. It wasn't about not having learned it yet, it became about being able to figure it out on the spot. I felt that I had all the resources to get any problem right, even if I had no formula, set method. Hope that helps. Literally, a massive part of the test is overcoming the hurdles you set for yourself.
