Comment:

If you skip(fail), can't pay attention, can't understand, can't take decent enough notes, or for any other reason fail to answer his question correctly two days from now, your grade drops. Also on test weeks hw is due wed not fri, I lost my A over that i think, i might have still been a bit off though so no worries.

Comment:

He is truly the worst teacher I have had in my entire life. He gives quizzes every class period over the homework assigned last class, so don't expect to do well on the quizzes unless you have finished the entire homework and completely understand it. The tests are too long for the time given and he picks the hardest questions. Do not take him.

Comment:

Alspach wants you to succeed but only if you deserve it. He gives a lot of homework and there are quizzes every day (easy if you do the HW). His tests are a little tough but he gives a study guide and he curves the tests. His lectures can get long, boring, and confusing but he really loves math and tries really hard.

Comment:

this is the worst professor I've ever had. he has office hours but makes you feel stupid for even stopping by to ask your question. As if the answer was obvious. he gives you a quiz every class period of the 20 hw problems he assigns after each class and will only grade 3 of 30+ problems on the HW, so those random three better be correctly done.

Comment:

Lecture was theory based and even if lecture wasn't completed we would still have a quiz on it. This professor made me feel uncomfortable to ask questions. He would sigh in frustration. I don't drop classes and I had to drop this one. Tests everyday, about 20 HW problems due every Friday and he grades only a select few a 5/5 was rare.

This was the hardest class I have ever taken. Instead of using basic examples he teaches and proves theories that are ridiculous. and then he expects you to be able to solve problems that he didnt explain. There were quizzes where literally everyone in the class failed.

Lectures are ALL theory... Guess what, theory doesn't help you with the homework, quizzes, or tests. Take a different teacher or you will hate every day of your life between class and days off doing homework

Comment:

Gives quizzes, fairly easy, ZERO TIME TO COMPLETE. I know exactly what to do but barely finish. If I copied the answer, I might have 30 seconds left. Harsh grading for not writing out in words what is happening. I emailed him to explain nicely that no one finishes; he flips and says that tests are 6 probs in 50 min... NO ONE FINISHES THOSE EITHER

Worst teacher ive ever had in my life. Never had to drop a class until now. You'll leave class discouraged and frustrated. Has quizzes everyday that cover his absurd homework assignments. Do yourself a favor and pick another professor.

Flat out horrible. Easily the worst math professor at Oklahoma State. Doesn't teach at all, and then expects you to know everything about the particular section and then some.

This professor was very bad. I have A's in all classes but I couldn't understand what he was teaching, so I had to drop that class and retake it.

Comment:

Dr. Alspach was a really good professor.  I took him for differential equations.  He was pretty easy to understand and I felt like I really understood the subject at the end.  The tests can be difficult but aren't bad if you do the homework, and he gives lots of partial credit and curves.  Overall a very worthwhile class.

Comment:

The worst professor I have had my whole career as a student. I am one semester away from graduating with a dual major in Math and Physics, and because of his harsh grading, and his lack of teaching I made my first C. I even went to every class. Stay away. The comment below is obviously from a fellow classmate, and their review is 100% accurate.

Comment:

Too much material is covered. We finished the entire Vector Calc book. He grades harshly & gives no partial credit. His hand writing is horrible & his lectures are all theory. Half the class dropped & less than a third ever went to class. Do not take this professor! You'll learn nothing, and you'll hate your life all semester.

Comment:

If you haven't had calc before, get another teacher. Gives a generous curve on every test. Not too much homework. Gets deep into the theory sometimes. Take notes and read the book. Attend class or you'll lose 30 points off your final grade. Good office hours. Sometimes doesn't answer questions well.

Extremely hard. I got an A in AP calculus BC in high School and his class was a struggle. He knows EVERYTHING there is to know about every concept of calculus, and often expects the class to too. Do not recommend.

Comment:

The class was much harder than necessary:I talked to other people taking the same class under different professors and their classes were much simpler. I had already taken Calculus in high school and found this course very difficult. The problems on tests are often very different from the practice ones. If at all possible take another prof's class.

Comment:

Awful teacher. Class average had to be a D. you have to write a ridiculous amount to get full credit on tests. No one finished his tests. His pride in being better than everyone at math is amazing. I hope I never have anyone as difficult as him in my life. Get out of his class if you like having high GPA. Lost my scholarship bc of him.
