He records the lecture and post it online. However, there is Iclicker questions that are not recorded. He explains very clearly and if you memorize his powerpoints and know the material you will do great in his exams. I never used the textbooks or Internet to study or further understand the material but listened to his records and took notes.

He is great! If you listen to the recorded lectures and take notes, half of your studying is done. Just gotta learn everything by heart! He explains quite well, and wishes best for the students. Give tutorial session before each exam where you can just ask all your questions. Plus, If you do badly in one of the midterms it can count for 10% ..

He's a really good teacher but the midterms are difficult, at least in my opinion but that shouldn't stop anyone from trying because this way may be the best way to learn how to prepare for future classes for those who don't test well. Listen and take good notes and that A is yours.

The class is very heavy, but Sacher makes it as approachable as it can be. His slides are thorough and informative. The tutorials are really enjoyable and complex, and the fact that they're graded on participation only is nice. This class intimidated me but in the end Sacher gives you everything you need to get a decent grade.

Dr. Sacher has got to be my favorite professor at Concordia. His lectures are well-structured and very engaging. He asks many questions during lectures that help you consolidate the information you learn about. Attendance is mandatory. This class is quite heavy in terms of material but doable if you stay on top of your studies. Exams are fair.

honestly loved biol266 with this prof. He is super kind and approachable and can make hard concepts seem easier by relating them to something easier or making jokes. 100% would retake

HE IS THE BEST!!! listen to his lectures again and again and then again. You will feel he speaks the whole exam during his lectures. The only prof who can actually teach.

Sacher's teaching is good although the course is very heavy. His exams are fair and straightforward. He never posts video lectures though, only voice memos which you have to match to the slides. his slides aren't informative and just filled with pictures with many gaps left to your mind to fill, he didn't use the book which was confusing.

if you have the chance to take him DO IT!!!! He is a great prof. His midterms were harder than his final (specially the second midterm so start studying early). Go to the tutorials they were super confusing but easy points. Kinda mean when you ask him questions but still tries to answer them.

He's a good professor however the material is tough. There is a lot to go through so you cannot fall behind. He uses TopHat to grade participation in class so i would recommend attending every class. Another thing is the tutorials are quite useless. However, participation is graded so you should still go. But it does not help with studying at all.

He is overall a good professor and there to help if you have questions. The material is a lot and his exams are based on a lot of detail on the chapters, so be ready to study a lot. Tutorials are easy grades all that matters is attendance, lectures sometimes boring and he also has tophat questions for participation so be sure not to miss that.

He's good. The material is hard but dr sacher tries his best to guide you through it. His tests are very fair and there are no trick questions. Tutorials are a good way to get exposed to papers you might read in later courses but they're not relevant to the material tested on.

Lots of material in the lectures but presents it well. Exams are fair but long and the final exam was surprisingly not that hard. Tutorials were confusing but I liked the material in them once the TA explained it. Gives homework questions a few times per week, but they were helpful and not tooo hard.

His lectures are so clear and he emphasizes what you should know for test. He also recorded them, which I loved. His tests are sooo easy as long as you study/memorize his PowerPoints. A+ is very achievable if you put in the work.

I'm a graduate student working with him, and I have to say he's been amazing! He's given me some really exciting experiments that are super engaging. If you're looking to develop your science skills, I definitely recommend him! However, it's a journey that takes time, but the rewards are absolutely worth it, you'll have memories you won't forget!

The course is extremely heavy and there's a lot of studying needed, but his lecture slides are super clear and he does an amazing job explaining everything in a way that makes sense. The midterms are super specific so study details you think you won't need. The tutorials are completely irrelevant to the course but you get full marks just for going.

Professor Sacher has been my favourite prof so far! His lectures are super detailed and he really goes through everything. Go to class because he does TopHat questions. Go to class, take notes, make notes, and study continuously. It's a difficult class but not that hard if you simply keep up and try!

Very nice and engaging prof. The course is heavy on memorization. Must attend class cause there are graded in-class questions. MTs are straightforward, I found the final easier than the MTs. Tutorials are unrelated to test material, but go to them all since they're a free 10%. If you memorize the slides, an A is easy. Midterm averages are high 70s.

An amazing teacher. The material is difficult but if you know the material on the lectures, youll do great in his class. There are no surprises on the midterms or final, everything he grades you on is found directly in his powerpoints.
