2-4 hrs/week

this class was not too bad. I would say just read the textbook because literally everything comes from there (hw, lecture, exams, final project) and stay on top of the work.

2 or less hrs/week

the content personally wasn’t interesting to me so i never showed up to class but ended with an 100, everything is online/take home so overall super easy psych class

This class is a completely different grading style compared to your normal college course. Your grade is dependent on how many objectives you pass by the end of the semester rather how you did on each objective and assessment. I think it is easier than normal Calc 1, but some would disagree. It is less stressful throughout the semester, though, because each assessment is no stakes (you can literally get a zero on MANY and still get an A in the class).

Not as bad as people say it is. Do a lot of practice problems and you should be fine. Helpful for Calc 3.

Johnson is a great professor, and really passionate about his teaching. If you pay attention somewhat or know some calculus beforehand you will do well in the class.

I really like professor Johnson. He cares so much about the material and his students. The first exam might've been a bit too hard but the final was very fair and we had 2 take-home exams. Psets could get a bit lengthy, but the exams were always easier than the Psets. Would recommend if you love math!

Professor Johnson was a great professor to take number theory with. He is very knowledgeable about the subject, and he did a good job explaining the material during lectures. I felt the exams were fair, and we were given two take-home exams to help de-weight the in-person exams. He also offered lots of extra credit opportunities on PSets and exams.

5/10/2024

Johnson is the best professor I have had in the Math department. His lectures are great and he cares about the material. He also cares about his students and goes out of his way to help students. Highly recommend taking this course with him.

5/10/2024

He was great.

This class is so disappointing. As a math major, I was so excited about Number theory and cryptography. but this class has been more annoying than fun and has destroyed my self esteem. Prof. Johnson is a good lecturer but makes the class so inaccessible almost. The problem sets take at least 10 hours and the exam was graded SO harshly.

3/21/2024

Bro didn't release exam statistics because of how horribly it went. The only thing that can save me now is Jesus.

3/21/2024

What went from being my favorite class at the beginning of the semester is now my most dreaded, scary, difficult, impossible class. He's not understanding of our time or responsibilities outside of this class and expects us to spend hours on HW while giving us the most impossible exams. Steer clear of this class if you want to keep your sanity.

3/21/2024

I can't take this anymore. I am spending so much time on this class yet doing the worst in it. I feel like I've lost my sense of pride in my work and all sense of feeling about how I perform. Someone said the class feels inaccessible and I've never agreed more. I wish i had advice to not take this class before i jumped in head first.

3/21/2024

I want to like this class so bad because Prof Johnson is nice, the content is interesting, and people in the class seem helpful. It is just way too difficult and feels like a full time job with overtime. So I have come to despise it which definitely makes me feel a little sad as a math major.

3/21/2024

Even so much as thinking about this class genuinely makes me want to cry

3/21/2024

Came to rate my professor cuz I thought I was the only one feeling terrible about this number theory class. But looks like theres a ton of others that feel this way as well. I guess it speaks for itself, just don't take MATH4351 with Silas Johnson.

3/21/2024

I genuinely do not think it is possible to get an A in this class. The HW assignments are graded so harshly, and the exam averages are incredibly low.

3/5/2024

Prof. Johnson is a good lecturer and a terrible grader. He wanted us to learn how to write rigorous proofs so he took off major points on the weekly problem sets for the most trivial errors. Not to mention the problem sets probably took around 5 hours on average to complete. I wanted to like him, but this class was more annoying than fun.

2/17/2024

10/10 professor- easily the best for Calc 1. Tests aren't too hard- definitely use the Study hub section that he posts on canvas to study because he puts a lot of extra practice there. Textbook can be found for free online and is only used for optional extra practice. Homework is much harder than exams, but you'll get that with every math prof.

1/24/2024

Can second what others said. Probably the nicest person in the department but lectures are physically impossible to follow. Copies the textbook 1:1 to the slides, rendering them useless in class. Problem sets are easy and she gives tons of extra credit opportunities tho. It's hard to figure out what content is actually relevant for the exams.

1/17/2024

Excellent prof, teaches really well but includes a lot of extra information that would not be tested.

1/8/2024

Professor Johnson is a nice guy. Lectures are helpful but not mandatory (he may get off track during lectures by trying to prove theorems but it's okay). Tests weren't too hard. There were also many opportunities given to receive extra credit. If you pay attention and study a bit, then you'll be fine. Textbook isn't really necessary.

12/29/2023

ECON 352 is a wonderful survey-based course and you can learn a lot. However, the professor's exam is almost out of the lessons. Most of the exam questions are not prepared and you should find these through the lecture PPT yourself, some of them are subtle and sharp. The professor does not have a clear lecture thought, the key points are scattered.

12/25/2023

worst prof ever

11/29/2023

If you are present for class and pay attention, she will point out important slides to study for the midterm and final. She is willing to help outside of class when and if you need it.

5/22/2023

Enthusiastic about math, but must put lots of time into calc outside of just understanding lectures. Well-organized Canvas page. Webwork was stressful & above exam-level difficulty. Master practice exams, bc final grade is based on exams.

1/16/2023

Very nice guy and consistently accessible outside of class. I did not find his lectures helpful though. He spent a lot of time talking about hypothetical problems or working out problems that were WAY more difficult than what we were actually expected to learn. Homework was very difficult too. Master the practice tests and you will do fine.

1/5/2023

Prof Johnson is clearly passionate about math and teaching. He cares about his students and wants them to succeed. His enthusiasm made me appreciate calc more. The practice exams were very similar to the actual exams.

12/30/2022

Johnson cares a lot about math and making sure student feedback is received. But, he spends too much time in lectures talking about things that aren't on the exams and that are useless. Sometimes classes drag on and he would ask us to participate in the most random questions. Exams are only 18 questions, so be careful on that.

12/28/2022

She really doesn't teach you anything. The idea of the course was so cool and interesting, but she copies the textbook word for word into a powerpoint and then reads directly off the slide. It was hard to stay awake. 70% of your overall grade was exams, and her lecture style does not prepare you for the exams at all. Overall not a good professor.

12/20/2022

Wasn't really a fan of Silas's lecture style/lectures in general hence the 3-star rating, but you can tell he cares about his students and really loves math. He is accessible during office hours and the class itself will vary in difficulty depending on your background with Calculus, so try to stay on top of your work.

12/7/2022

Silas Johnson is a phenomenal professor. Although I haven't completed my first semester here at WashU, I highly doubt my opinion of Dr. Johnson will change in the next month or so. In general, he's a great professor who cares about his students and teaches well, and the course itself, Math 131, is made rather easy through him.

10/27/2022

Super interesting and helpful math teacher! Glad I took him for Calc I because he really helps you with any problems you have during office hours. Tests are also very similar to practice exams, so no surprise on exam day :)

4/3/2022

make sure to go to your subsection meetings... it surprisingly affects your grade more than you might think

12/22/2021

Her class is discussion-heavy, but the students have to lead the discussion. In class, she doesn't really teach. In individual meetings, she's intelligent and helpful. She knows what she's doing, she just doesn't teach in class most of the time. Really smart and friendly in individual discussions, but wouldn't take her for a class again.

12/21/2021

You can tell he's passionate about what he does, and he seems to genuinely care about it. If you stay present during his lectures and follow his lines of reasoning, you will do well. His tests are very fair, which I always appreciate. There will be almost NO random stuff on the tests that you've never seen before, so just know the stuff from class!

12/13/2021

The class was genuinely interesting and it should also be an easy A if you follow the instructions. Professor was also willing to give clarifications at any point.

8/23/2021

Explained math concepts very well. Goes into depth about the proofs for theories and math problems.

2/24/2021

Prof. Silas is one of the best math teachers I've had. He gives very detailed explanations of the material we're learning and he's very accessible outside of class. If you're ever struggling make sure to go to his office hours! He's really cool and an overall good teacher. Calculus is hard in general, but he tries his best to explain it well!

12/4/2020

Prof Johnson is super nice and adapted the class extremely well to the pandemic. You can tell he actually cares about his students and really loves teaching. He is very receptive to emails and is helpful in office hours. The class is pretty homework heavy and was a lot of work but you get the grade you work for. Would definitely recommend.

5/22/2020

Smart and puts a lot of effort into helping students. If you come there to learn, you'll enjoy it. Class isn't particularly hard, but in case you just want to pass, there might be easier choices.

2/11/2020

Dr. Johnson is a hit or miss for many students. While I attended almost every lecture, many of my friends chose to skip and did well in the class. His lectures can be very boring but he truly loves what he is doing. Exams are super easy if you know the content on the practice exam beforehand.

1/5/2020

After the first month I can count on my hand the amount of time I went to lecture. Johnson is a good guy but I didn't get any benefit from lectures that do not reflect the hw(quite a bit of it), subsection(also unhelpful), or exams. The information is in the slides(somewhat) and textbook but I self-taught through the class with the help of pltl.

11/13/2019

He made so many mistakes on webwork (and in ppts). For example, the very first webwork had a question that took me 96 attempts to get the right answer and turned out to be him entering the wrong number. Every time he made a mistake, I had to waste more than half an hour on the wrong problem doubting myself and asking friends who are better in Math.

10/21/2019

Worst class I have ever taken. Lectures are dull and slides are boring. The last 3 classes the professor has sat down and read from the slides (that I believe come with the textbook) and didn't move a single time. Not worth your money. It's a shame WashU allowed this teacher to teach. She is clearly smart and very nice, but not a good teacher.

10/10/2019

Every lecture consists of her sitting at the front of the classroom and reading directly from the powerpoint slides. She erratically skips slides just to make her lecture fit the class period. She is VERY nice but does not prepare for lecture at all. I learned more in high school economics.

10/3/2019

Dr. Johnson is one of the most amazing professors I have ever met. She provides students (at least me) with very personalized lectures and gives us detailed feedback. No matter what your level is in piano performance, she can always make your MUS 159 and 160 class worth the effort you put in. Highly recommended!!!

1/15/2019

hes a very fair professor and really good in my opinion. Do your work and do all the problems and you will get an A almost guranteed
