So... the test didn't go so well. I thought my score was going to be a little higher than it was but there was many questions on the test that I thought were way too hard. I think that a class like this should be graded by how well you understand something. The questions to me are way to in depth and could be a little easier. We went through chapter 14 extremely fast for my likings and could have spent a few more days on the HNMR and CNMR spectrums in my opinion. Also, I feel like if we had a test review day things would go much better. Another factor for not doing well on the test was the need of more time. I felt very rushed and yes! I understand that eventually some of us will take tests like this that are timed but at the same time I think because this is an actual class we should have accurate time to do the problems and questions.
Some questions on the test that i didn't expect to do were number 15 and number 11. I think these questions are doable but could be worded differently and broken down. I think that time could have been saved on question 15 if the graphs were given and then we provided the different frequencies, the same for number 13.
I expected to see more questions that were similar to our sapling homework. There were a lot of Sapling problems and I feel like doing them didn't really prepare me much for this test even though on the past test I think Sapling did provide with studying assistance. A question that I really thought would have been on the test was counting the number of signals CNMR and HNMR for each compound. That was kind of a simple question but yet would have given us a chance for some easy points. Every test needs a few of those.
I did horrible on this first test, but I think with tutoring i maybe okay next test. I am doing pretty much all of the practice problems so therefore i should do decent I hope.

Muddiest Point!
So I have had a couple muddiest points thus far... Electromagnetic radiation is really confusing. I cant really grasp the understanding of the equations but i found information on Wikipedia that can provide me assistance (http://en.wikipedia.org/wiki/Electromagnetic_radiation).
Also I cant figure out how you are supposed to match a compound to a given mass spectrum. With more reading i have found out that you have to look at each of the wavelengths and the peaks to determine which compound is which.
I am not 100 percent sure about the base points and highest points of individual mass spectra. I found a great website that explains this little by little. (http://www.chemguide.co.uk/analysis/masspec/fragment.html#top)
I think with more studying and reading i will be prepared for this test hopefully.
