Today I totally bombed my physics (Mock college entrance) exam. I mis read questions, pressed the wrong button on the calculator etc.. This has always happened to me. Whenever I do an exam I both figuratively and literally crumble to pieces. (dry skin) Does anyone have any tips for...

I'm wondering if I can make this task easier, since I've ruined a lot of grids lately. Currently, I'm trying to use tweezers, but I lack the subtlety to grip them firmly enough without bending them. We can't use vacuum on them since it would potentially contaminate our samples. I've thought...
