LS23L was not difficult, but the PCR is NOT a fair system and really takes a toll on your overall grade. The labs aren't very interesting, but they are easy to complete and you don't need to do a lot of prep for them. If you are taking this class, it's probably a requirement, so it won't take up a lot of your time or be super difficult, but just be weary of the PCR assignments and focus on those.

easy class, learned a lot

I took this class Fall 2018 and ended up with an easy A.
The CPR assignments are truly annoying. I did not do well on them overall (6/10, 7/10, 9.5/10), so I thought my grade would suffer. There is so much pre/during/post lab stuff that is easy to get 100’s on that it didn’t make any kind of difference for the final grade — don’t stress.

They say they recommend you take this class while you take LS7C, but I disagree. Take it later. The bs from this class might confuse you.

I didn’t find the videos/“lectures” helpful so i didn’t watch them. Just skim that day’s lab in the lab book before lab.

This final was easy multiple choice (I just skimmed the lab manual and looked at the online quizlets).

My TA (Alonso) was great. This class is heavily TA dependent, I would assume, since they are the ones with you in the lab.

The class is overall fun and doable for a person taking other hard and time consuming classes. It doesn't have a big workload. However, the CPR system is a killer. The professor thinks the CPR system is effective in teaching students how to write a research paper. That is absolutely not true. When grading other people's work you are only allowed to deviate from the mean by 2 units. So if the scale is out of 10 you are very likely to give most people a 6 so that you are in the range (no one will give it anything higher than 8 and most probably lower than 4) At the end you get your points because other people grading that person's work also gave it something around 6, but the person whose work you graded did an awesome job but still lost 4 points because of you. You can't blame the grader because they were just trying to be safe and grade it in a way to remain within the range. This is not the right learning environment. The students' writing does not improve they just learn how to grade other people's work to remain in the range. If you attempt to request a regrade for your work the professor will look at your work and try to regrade it (you're most likely not gonna get a regrade, just a feedback directing you to the resources on CCLE). but how effective is the professor going to be grading your paper if he hasn't looked at anybody else's work? Professor needs to have an understanding about the entire classes' performance to grade your work based on how well you did in comparison with the class. Otherwise, someone might have done a worse job than you did, but was lucky to be graded by students who didn't care and gave them a high grade.

The review below hit all the main points. I would just like to add a few things.
--Most of the questions can be found on quizlets. Most, not all.
--This lectures in this class are flipped lectures. That is, you watch a video of Dr. Pflugel before class, usually 20 minutes in length. The flipped lectures have all the content you need to know for what you are about to do in class. Dr. Pflugel himself does have an accent, but you should just want the flipped lectures with subtitles. The class lectures are headed by a TA. A lot of your grade in the class will be depend on your TA. As long as you participate, do the class worksheets with your lab group, you are pretty much set.
--Overall, the class is pretty easy, more busy work than actual work. CPR can be pretty annoying, simply cause people just give you a low score but will tell you that your work is fine. Just realize, that if you get an average of 6.67/10 from your peers grading your CPR assignment, and do everything else perfectly, that's already a 90% on the overall assignment!

The course is pretty simple and a minimal stress class. You do the prelab quiz, you go to lab, you do the postlab quiz. Every couple of weeks you complete a CPR writing assignment, which is useful for learning scientific writing skills, as well as learning to critique others. This critique really does make your paper better, you learn to be less lenient with others, and also more strict on yourself. However, sometimes your papers are graded very harshly and your self grading is thrown out as too far off, and sometimes when critiquing other people's papers, the other students are too lenient so your grade is thrown out as too harsh! It can be very frustrating that a large portion of your grade depends on the efforts (or lack thereof) of 3 randomly selected students. The calibrations are especially difficult to get within range as well. Dr. Pfluegl is a fine professor; due to the nature of the class there is really no need to ever see him unless you have a question your TA absolutely cannot answer. His online lectures are well structured and self explanatory, and he is very open about students coming to him if they have any concerns, but this shouldn't really ever happen in this class, which is, again, pretty self explanatory. Overall, I have enjoyed this class and learned a lot, my only real issue is with the labs sometimes. Often, the labs do not need to take up the whole 3 hours, and the TAs and LAs are forced to fill it with busy work due to the policy of not leaving early, even when there is truly nothing else to do or learn.
