Students complained he's a bad lecturer, but these students were def not reading the book because that explained everything and he goes over it again in class. He does have a stutter/lisp and he would say the wrong thing and have to correct himself. He's really nice and understanding. Tests were hard but he didnt write them- I ran out of time

I had Blair for Ch171, and while I took it lots of people complained about Blair, and I dont understand why. Blair is knowledgeable, quite caring, and gives very fair tests. If you read the book and attend the lectures, you shouldnt have trouble getting a decent grade. You get out of it what you put in. I got a B+ and I think I gave a B+ effort.

Professor Blair is a very kind person, but a bad professor. We had to skip material because we fell so far behind in the course. In addition, his lack of ability in understanding simple questions makes it difficult for students to understand and clarify concepts. Overall, don't take the course from him if you're interested in taking the MCAT.

Writing this review for the 421 lab. It sucks. Labs are EXTREMELY unorganized and you WILL be confused on how to do the procedures and the postlabs, guaranteed. Prelab slides are decent at best, sometimes forgets a lot of important information about the experiments and postlabs. Also not the best at explaining in prelab. Go to office hours.

Lots of homework

Disorganized and not helpful for students. His curve somehow lowered my grade. Day before our final our online textbook went down and he didn't answer any of the students. Have taken biochem in a masters program since, and it was taught much more effectively.

Dr. Blair is a great prof, especially if you don't have a lot of chem experience (didn't take ap chem in hs). Unfortunately chem as a subject is pretty hard but he does a good job teaching it. The course is very time consuming with the lab, prelab, lecture. It's also a bit expensive, but if you study the material from time to time you'll do fine.

Professor Blair is truly the nicest Professor you will work with at BU. Even though his classes and the material in them are challenging and there is a good load of work, Blair genuinely wants all of his students to succeed. If you are struggling, talk to him and he will help you.

Blair is caring, wants everyone to succeed and loves hard-workers, talk to him he knows who attends and cares. Attendance is mandatory, exams are difficult and intellectually challenging because the concepts are difficult, do the worksheets, ask questions, make study groups, ask blair in OH, study the slides and understand the concepts.

Challenging class with tough exams. As seniors, we expect rigor, but Blair's approach seems pointless. Minimal homework graded for completion is ok but unhelpful for exam prep. Discussion worksheets were manageable but far easier than exams. Prefer graded homework for better test preparation. Dr.Tolan would likely teach this class more effectively.

Took the class during the summer, so the course was quite intensive, yet Dr. Blair took the time to answer questions and clarify concepts for both lab and lecture outside of the class times. The exams were straightforward and covered what we went over in class quite fairly. Hard class though.

Blair is a really nice guy with plenty of office hours for you to go to if you need extra help. He's better at answering questions one-on-one rather than in lecture. He curves the final grade and even dropped our lowest test score for both 171 and 172.

Since CH171 and 172 are both "principles" courses none of the content is too in depth, and he does a good job summarizing what you need to know. Exams are fairly frequent but aren't too difficult, and the homework is easy. Blair's lectures are structured well and make topics seem relatively simple. He is also very nice

CH171 really isn't that bad. Go to lectures and do the homework and you will do fine. Blair is a great lecturer and makes the topics much more digestible.

Dr.Blair is the sweetest lecturer, and I genuinely do not know why people give him bad reviews. Blair has his teaching style and provides the funniest "marriage cheating" analogies. He has his way of telling you to shush by asking, "Do we have a question here?" Anyways, I would recommend taking this class with Dr.Blair.

For 171, not as hard as people make him out to be. Teaches concepts in an easy to digest manner using humorous analogies and emphasizes conceptualizing the content through practice problems rather than relying on memorization. Honestly I didn't even use the textbook. I just did all the problems assigned through discussion and hw, and I was fine.

awesome sweet dude! idk why his past reviews are mad evil- the material is inherently a bit difficult to understand in just one lecture so it's not really his fault. there's a lot of elbow room to boost your grade and u gotta pay attention the entire time while he teaches but i found him engaging! just study a lot and you'll pass #TeamBlair

He does not know what he is teaching and it shows in the lecture. I'm not sure if he understands the material, but the fact remains that he cannot explain physical biochemical concepts to save his life. I'm sure he is knowledgeable on other topics, but someone like Prof. Straub would be better at teaching this class. Feels like Gen Chem 2.0...

1. 172 is harder than 171. It's very memorization heavy, but there is basically no math. 2. Have a good Gen Chem background. Know your IMFs and hybridization REALLY well. 3. Go to office hours and review your discussion packets and Achieve HWs to study. You'll do fine.

I love Blair, he makes these topics generally digestable in lecture and if you don't understand something he is great and answering person based questions in office hours. I wish he could teach every one of my classes. one homework due every couple weeks and the many tophats for participation make it an easy good grade to get.

Dr. Blair is disrespectful, condescending, and unhelpful. His grading rubrics have hidden items so you are bound to get points off on Labwork and he never supports a student but rather works against them. Do not take 421 if you don't have to.

Blair's lab procedures are hard for students understand, it was sometimes (at least not always) blur. He don't give TA answer key timely so that TA have to do office hours without answer keys, which makes answer from TA inconsistent!!!! So that different TA will you different answers. Furthermore, the gradescope grading was unfair...(word limited)

In-person he's great! He explains questions and pre-lab was v helpful for lab. BUT He's a tough grader on post-lab assignments and will take points off for sometimes random things not specified. Mistakes that could be fixed in following post-labs, but they aren't graded in a timely manner. (labs from October haven't been graded and it's the EOS.)

Doesn't provide a rubric, so we never know what he expects from each post-lab. Takes points off for small things that you wouldn't expect. He wants feedback on the course, but is never open to it and gets defensive. TAs are not on the same page about grading criteria, so even if they say it's right, it is usually not, so be aware during postlabs.

Absolutely awful lab course. Blair gives no real guidance and says “you should already know this.” He grades every tiny detail and will deduct in multiple sections for one mistake. I went to TA office hours constantly, but their advice was rarely helpful, and I still lost points for things they specifically told me to do. Ruined my biochem grade.

Extremely dull and unengaging personality, with constant yelling for no clear reason. Biochem post-labs lack real analysis, yet grades depend on guessing what he wants, making effort and understanding irrelevant. Feedback is vague, support is minimal, and it's interesting that both he and the TFs fail to meet basic expectations. Utter waste of time
