for that g' h ' stuff you need to take g'(h(x)) * h'(x) I seem to recall a similar problem on one of the problem sets yes i did the same and yes i've seen that in one of our problem sets also, wow i thought i did wrong since there were alot of space given for each one i was like wtf? so the first one is 20 and the second one is 12 hopefully.... a) g'h(0) x h'(0) b) h'g(0) x g'(0) something like that....

I can't remember the exact numbers I got but I think that once you understand the procedure you have to go through. Notably multiplying by the derivative of whats inside there is not much room for error.

I don't know about everyone else but I thought the test was brutal! If I passed I would be surprised...I seriously wanted to When is the last day we can drop this class?

The questions on the test were on the whole pretty familiar, but some questions, like the ones worth the highest marks required logical thinking and understanding (which is fine), but I don't feel that I had the time to do that thinking. I didn't even do the last question at all! IMO the test was too long.
I'm starting to really get worried now since 60% in the course sounds like some kind of fantasy. What's worse is that usually when I don't do well, I say (like other people I suppose) we'll I should have tried harder, that I should work harder. I can honestly say however, that that just isn't possible. I don't always blame others for my failures (eg. the test writers) and admit it when I'm at fault, I tend to feel guilty if I feel that I didn't try my best, but you know I'm not getting that feeling here since I did try so much. Either I need some massive overhaul on my exam and review technique or that test was too long.
Wasn't having to do that graphing question without a calculator unneccesarily time consuming? I did like half the question (didn't draw the graph at all - another 5% down the toilet) and then felt I had to move on since I'd never finish. Each time having to check whether a critical point was a max/min by substituting by hand or in my head only shows the examiners whether I know how to do grade 9 substituting, yet most of the question involved doing just that.

Don't get so down... from what I've seen this test was brutal for most everyone in this course. Since at the end of the year they pretty much have to have a course average somewhere between 65-70%, as long as you believe you're par with the majority you'll do ok. Meaning, if the average for this test was 40% or something like that, the next test we can expect to be easier (don't hold me to this though ). After all... they do need a certain number of students to get over 60% to admit into the CS program, don't they?

I heard that the average is curved to a 60 but that could be wrong. In any case the test is done! regrets and hurt feelings aren't going to change that. We can't expect more from ourselves than our best and hope that takes us to places we want to go. However that said; we can put our best effort into something inefficiently. I know in myself for example I need to rethink HOW I study, not necessarily the amount of effort I put into studying.

>>>I heard that the average is curved to a 60 but that could be wrong.<<<
I'm pretty sure I heard Uppal say their goal was 55% for the class. So even if you are at or near the course average, you are screwed.
I can't believe I got that damn composition question wrong. So SO SO many stupid mistakes coupled with the questions I had no idea how to do. Well, I'm not worried. I'll get a 95% on the next test! It's possible! Yes...

I, too, found the test extremely hard...much harder than the first one, in my opinion. Clearly, especially when you're not given the use of a calculator, the answers should be nice and neat, especially for the critical points on the graphing question. I did not feel like I had nearly enough time to work them out and get some crazy answer, so I had to leave it without figuring out all the critical points. THat of course, caused my graph to be all screwy. On top of that, I found that the hard questions (the 10, 10 and 15) were EXTREMELY hard. I thought the last one was okay, but the max/min I had problems with, only because I misinterpreted the question, which in my opinion, was not very clear on what exactly you're supposed to be minimizing. (It didnt state that the line had to cross the axes, which would have made the question much clearer, and wouldnt have really given anything away). Instead, I was thinking that it could really go any which way, and blah, I didnt even have a chance to go back. I know I shouldn't blame whoever wrote the test, I just hope that I wasnt the only one to royally screw up (it sounds like I'm not) and then they'll see that the test was a tad unfair. Just my $0.02, which is probably close to the mark I got on this test.

The way I see it with the max/min question is that the line did not in fact have to cross both axes and you are trying to prove that the minimum will occur when it doesn't so the area of an open solid is zero. Its like me asking what is the area of this bracket ]

I figured as much, but even still...that seems sort of silly to me. I mean, wouldn't that mean that you didn't have to do the whole problem, just state the obvious answer.
Either way, I think the question was sort of ambiguous, and there's no reason why they couldn't have put something a little bit more straight-forward on the test, especially considering the "insane-ness" of the rest of it.

Hurrah for Suicides! I was going to jump off the McLean Physics Tower, but after not being able to break through the doors at the top, I gave up and remembered what my TA told me. Which he also said not to tell anyone else he told me He said that if I was consistantly getting 60's in all my problem sets and tests, then my final mark would probably looking like a mid 80. Suicide delayed until after next math test Lou
