After nearly a year, I came to check in again, hoping that Siegel can complete the zero point as soon as possible. .

Professor is very intelligent so sometimes he goes faster than he realizes so that can make him hard to follow. exams and hw are very rigorous but he offers help in lecture so go to lecture!! overall fair course but study your class notes because homework and exams are a much trickier version of the notes. overall amazing professor! kind & caring

I visited this website a few years ago, and I also read Teacher Zhang's documentary and sister's article, and I read it again today. After a years-long hiatus, Zhang published his Landau-Siegel Zeros paper today. Hope he succeeds again and becomes a legendary mathematician! Blessings from Shaoxing, China. Quoting Du Fu's poem again...

Amazing mind and equally amazing professor. A true gift to have learned from Dr. Zhang. One of the most brilliant minds of our time.

Don't take his online class, he is not a tech person. Read the PPT, and HW are difficult. Take his in person class. I drop his MATH 10B.

Practice exams are exactly like midterms and finals, with numbers and variables changed. Lectures are detailed but more than needed to do the tests problems., so they are not necessary Professor speaks very softly during lectures. I manage to pass the class skipping half the classes and just doing the homework and practice exams.

Professor Zhang's mind works so quickly that it can be hard to follow along with lecture. Fortunately, lectures are recorded and his notes are exceedingly clear. The homework can be rather difficult, but he gives many hints. The midterm and final are extremely faithful to the practice versions, and mostly computation-based.

Technology dumb, had him for online class, and his lectures were horrendous because he simply did not know how to work the online classes. Additionally, he will intentionally ignore your emails, if he does not understand questions you ask him. Grades harshly, and very not helpful with anything.

Despite his accent, Professor Zhang was able to explain things very clearly, which helped grasping the essence of abstract concepts. Besides, he gave practice exams that are very similar to the actual exams, so be sure to understand how to solve them. Homework also helped a lot if u do want a decent grade, and the workload is fine.

Tom is a really good professor. He is a really good lecturer.

Easy tests, exactly like practice. Good lectures but can be boring because he talks slow and quietly and he writes on a chalkboard. His explanations simplify things HEAVILY. Easy to understand, not very accessible outside of class. Definitely take him, helps you understand and is an easy grader. My homework grades were always lower than test grades

Midterm and Final were almost the same as the practice tests. Homework was half computational and half proofs but the graded problems were lenient. Sit in the front because his handwriting is small and his voice is soft.
