As far as p chem, which one? My school had thermodynamics (with kinetics) and I found that very straightforward. Main experimental test methods include: Water resistance/very water resistance/Waterproofness evaluation for make-up products and medical devices; volumizing and lengthening effect evaluation.

It wasn't all abstract because you can see the same results on actual instruments. To top it off the HPLC we have is so old, it takes like 15 minutes to run a single sample! When I was in college, that was THE worst taught course I took...the book was terrible and the professor was worse, not to mention the non-existent lab TA who left us to fend for ourselves. This quantitative analysis is done by considering the mass to charge ratios of the various peaks in the spectrum (Figure 1). And we skipped a couple of specs cause our prof wasnt familiar with them lol. Of course I don't know how much my experiences are relevant to you when I really didn't like organic and struggled with it (but not with biochemistry even though the reaction conceptions are the same-except you have an enzyme rather than the harsh conditions).

Includes an explanation of how the mass spectrometer works and how it can be used both to find relative atomic masses of elements and to help to identify organic compounds. There were 6 instruments we learned on, and each group started on a different one, so some of us were starting the lab on the very last instrument taught about in lecture, and some with the first instrument taught about in was incredibly inequitable as a learning environment that some students had the advantage of the lab and lecture being on the same instrument and others the disadvantage of starting with something they knew nothing about based on lecture material.
