<p>It’s hard if you go near finals. Desperation calls, people do anything. Obvious, no? I think the class might be curved in the end. The set points thing works when we had quizzes that you shouldn’t have missed (they were open lab notebook I’ve heard), but a final is totally different…</p>
<p>what do you guys think the cutoff for an A and A- is?</p>
<p>an A will be a 96/120. he said at the beginning that nothing will be curved and he’ll drop one lab.</p>
<p>well in that case, i need 11 points on the final.</p>
<p>well 96 is some sort of A
what is the cutoff between an A- and an A?</p>
<p>read your syllabus, no + - grading…</p>
<p>um i dont know which syllabus you are reading, but for pedersen’s chem 3al there is +/-</p>
<p>I’m reading the one that says…</p>
<p>Grades at the end of the semester will be assigned as follows:</p>
<p>Grade: A
Includes: A and A-
Points: 96-120</p>
<p>It seems pretty straightforward and he mentioned it in the first day of lab lecture.</p>
<p>i think what he/she means is the cutoff for some type of A is 96. </p>
<p>hopefully, it goes well for everyone. Good luck guys!</p>
<p>edit: oh he just posted same thing-nvm :)</p>
<p>I’m sure it will be lowered somewhat to account for GSI gradings. Otherwise, so many people would be messed up.</p>
<p>Dude I can’t belive you think there are no A-s.</p>
<p>^^that’s nice…</p>
<p>can someone explain to me why D-D interactions are temperature dependent?</p>
<p>No A-s? There are it’s just that he doesn’t put the cutoff on his syllabus. He determines the cutoff at the end of the semester.</p>
<p>Waiting: Well, DD requires a specific pos-neg lining up next to each other. Increase temperature, increase the motion and the orientation becomes all messed up, essentially preventing the needed alignment.</p>
<p>oh great thanks Batman :)</p>
<p>so what did you guys think? i thought it was pretty fair and there were definitely a lot of easy points. </p>
<p>for the sucrose in water effect on fp/bp-did you guys put no effect? i couldnt decide if sucrose is considered an insoluble impurity or not so i put it had an effect on one and not on the other question since i figured 1/2 questions right is better than 0/2, lol.</p>
<p>ya wasn’t too bad. I think it is soluble in water.</p>
<p>santa…you’re right :D. I asked a TA and turns out I confused it w/ another class!.. laugh out loud, i guess</p>
<p>That was pretty easy, i think my underestimation of it was just right. Sucrose is soluble b/c of the hydroxyl group so I put increase in BP and decrease in FP/MP (check out the sucrose bit [Chemistry:</a> Freezing and Boiling Points - CliffsNotes](<a href=“http://www.cliffsnotes.com/WileyCDA/CliffsReviewTopic/Freezing-and-Boiling-Points.topicArticleId-21729,articleId-21699.html]Chemistry:”>http://www.cliffsnotes.com/WileyCDA/CliffsReviewTopic/Freezing-and-Boiling-Points.topicArticleId-21729,articleId-21699.html)). </p>
<p>The only thing that I didn’t quite get was the damn splitting tree. I though I had that down cuz it was so easy. I was looking at my test for a good 10 minutes thinking "Daym!..why the hell am I getting 8 resonances?. it was a DDD right? </p>
<p>oh yeah and that NMR spec was soo easy…</p>
<p>i got a ddd, and the last question was just similar to ethyl acetate plus a ch2 in between the O’s or some ish no?</p>
