elen_nare Astronomy: Got 74%. Would have been better if I hadn't read apparent magnitudes as absolute magnitudes in one problem *headdesk* . Still, it's a good grade, I know what I did wrong, and I think I'm ready to take the final :D
Physics lab: got an 8.5! I don't have to take a final lab practical! I never have to look at a calorimeter again! (Yes, I'm kind of excited. The calorimetry labs took ages to do, and never turned out right! You can't really do that sort of stuff in a room where room temperature is rising because you have eight Bunsen burners going at once.)
Maths Analysis: failed it, got a 3. Kind of expected it really - no time to study, and I blanked out on what little I did know, so... This grade doesn't really matter, I'll just have to study more for the final.
------------------
Maths Olympics correction: survived it! It wasn't too bad - I was correcting the toughest problem, so a lot hadn't done anything (one kid wrote that it was an impossible problem... I felt sorry for him, but I couldn't do anything about it). However, what they were expected to do was give five weights, such that when adding them up in pairs the three highest and two lowest numbers matched those specified in the problem (I'll look them up and edit it in tomorrow)
ETA: better explanation of the problem: You have five objects with different weights. All ten combinations of two weights have been weighed on a pair of scales. You know that the three lightest combinations weighed 39, 43, and 44 kilos respectively, and the two heaviest combinations weigh 56 and 59. What does each individual object weigh?.
One of the correction criteria said that if by adding up pairs of the weights they gave, they got at least four of the numbers from the problem, they got half a point. Guess who spent hours adding up ten combinations to see if they got that half point?
ETA: clearly, my powers of communication are weak at midnight :P Lots of the kids would give five weights that were NOT the correct answers without bothering to check them. So for each one of those, I got to add up all ten combinations of two weights and see if they got at least four of the numbers they were supposed to, regardless of whether they were actually the heaviest and/or lightest weighings.
I'll post a bit more about this tomorrow.

The Math Olympics corrections sound *insane*. If they give half a point for certain combinations, you'd think they would list those combinations for you, right?
*hugs*

I put that very badly indeed, I think! I edited it so it made more sense. Lots of the kids would give five weights that were NOT the correct answers without bothering to check them. So for each one of those, I got to add up all ten combinations of two weights and see if they got at least four of the numbers they were supposed to, regardless of whether they were actually the heaviest and/or lightest weighings. You'd think they'd at least check their answers... ah well, they'll learn (hopefully!)
*hugs back*
