Well yesterday I had my last final of the semester. My semester was very challenging this fall, I had Organic Chemistry and lab, Physics for Engineering, Calculus 3, and an easier engineering class.
Chemistry labs are always frustrating. The amount of work you have to do for the 1 credit hour you recieve just doesn't seem to add up. You have to read the material, fill out the pre-labs, sit through the actual 4 hour lab (alot of the time you have to restart the lab halfway through), and writeup the lab reports. I swear most of the time your grade is based solely upon what TA you end up with. Some TA's are extremely harsh, others are very lenient. In the end you come out with the same knowledge regardless of how harsh your TA was. At the end of the semester the Professor looks at all the different TA's scores, and goes through a really funky grading process that basically entails raising the grades of those who were graded very harshly, and bringing the grades of those who were graded very leniently down. After that, your numbers are plugged into a database along with all of your quiz scores and your final score and something magically pops out. Basically... its impossible to have any idea of what grade you are going to end up with. That is how it is done here at the U, I don't know if its the same elsewhere. My TA gave me the same score for all of my papers. 50/50 points on my prelab, 40/50 points on my writeup, and it was the same for just about everybody else in the class.
The final for the lab was open book, but it was actually quite challenging. On the last page of the exam there was a 40 point problem (out of 80 points total) that asked for you to devise a labratory procedure that would isolate 4 different compounds with certain conditions. The thing is I actually hadn't made it to that problem or known it was there until the TA said there was only 5 minutes left for the exam. Frantically, I spilled through my textbooks and found that adding excess amounts of certain bases would turn certain things to a salt and adding excess amounts of acid would turn others to salts so I desperately tried to spill all the information I could onto my paper. "adding excess acid would turn this into a salt, filter the salt away, adding excess base would turn this to a salt... filter it away." It was an act of desperation and I was pretty sure there was no way that that was indeed the correct answer, but I was desperate and I was shooting for the partial credit. The funny thing is, none of the labs or procedures we had done all semester were in the slightest resemblence of that process...this is the reason why I was so sure it wasn't the right answer, but I was actually correct... and most of my classmates were wrong haha (a pretty unfair question huh?). I got 40/40 on that question and in the end did better than most of my classmates on the final.
I was having difficulty in Calculus 3 all year. I feel like Calc 3 is really hard... and kind of easy at the same time. Once you get your head around the initial mind warp that they place on you at the beginning of the semester the concepts are fairly easy. I guess the hardest part of the class was getting points to count towards your grade. You were graded based off of 4 exams, one of them being the final. The thing that was most frustrating was the teacher would write her exams with only 3 or 4 questions, and she doesn't curve them. So you miss one problem and you find yourself with a C. I just wanted to pull my hair out all semester. The final wasn't comprehensive, it was just like another midterm. So having two finals on the same day I had strategically split my study time based on the difficulty of her previous exams. I had studied the things we had gone over in class and things she emphasized because that seemed to be the trend of what she put on her tests. The final came around, and she had thrown us all a curve ball. Luckily there were more than 4 questions on the exam, but two of the problems looked completely foreign to me. It looked like everyone else was having just as difficult of a time as I was. You know its finals time when you can hear people sobbing during the exam.
I had been doing just fine in physics all semester. The class was probably the most difficult class out of the ones I had this semester (probably the second hardest class i've taken thusfar), but I had been doing just fine in it. I was looking at being above average with probably a B all semester, and the final came around and it just totally kicked me in the butt. I couldn't believe I had done so poorly on the final. I was pretty good at all the individual concepts and the normal story problems we had been doing all year, but for the final the professor had mixed multiple concepts into single problems and threw a bunch of little tricks in that just raped me. The teacher wanted a more defined line between the different grades so they graded the exam extra harsh as well. I'm frustrated because I didn't think I was doing that bad in that class. I'm very disapointed.
I actually really enjoyed my organic chemistry class, much more so than general chemistry. It was still a really hard class. We had been going through a fairly steady pace all semester and we didn't cover a whole lot of material (we had gotten up to substitution and elimination reactions), but in the last 2 weeks of school it was like our professors were stressed we hadn't gotten through the material so they dumped more material in the last two weeks than the whole semester (the dehydration-type reactions, the 5 or so different addition reactions, addition reactions of alkenes and alkynes, and oxidation and reduction reactions). It was very overwhelming and their (there?) were just a ton of things to memorize. One of the professors that taught the class was a big organic synthesis guy, so half the test were difficult synthesis problems. They'd give you a starting product and an end product, and you would have to "fill in" all the in between steps. They're difficult but I enjoy doing them. I studied really well for that exam too and I'm pretty sure I did better than most the class. I'm hoping I redeemed myself from my other classes with this final.
I hope I didn't do too bad on my other classes. I'm extremely disapointed. I have to have a certain GPA at the end of spring between my prerequisites to ensure major status and I hope I don't have to retake any of my pre-reqs. They only allow you to retake one, and if my GPA doesn't match up after that one "redo" than I will have to have some major changes in my projected life goals. I want to have a degree in engineering. The very thought of transfering to a chemistry or biology degree seems so lifeless to me, and I would also find myself amongst an ocean of 3.8-3.9 GPA'd students with chemistry and biology degrees that I would have to compete with when applications to med schools arise. I'm not saying that that will be what will happen but the thought of that window getting narrower is stressful.
