    PSTAT123 . Jammalamadaka 2 Years Ago

    It's nice to have a class where the professor truly wants you to get a good grade. Every step of the way he makes it easy to make up your grade or do better. The final was out of 115 points but he grades it out of 100. Dr. J is very nice. That said, if I could give him a difficulty of 0 I would. The class was not challenging in the slightest.

    He's a great professor. Alot of knowledge and formulas in his head so get ready to have alot in mind. He's very passionate about helping his student and he's more familiar with grad students who are committed student. Now with that said, if your class decides to not show up to class than expect a final based off of his lecture word for word.

    PSTAT120C . Jammalamadaka 1 Year, 4 Months Ago

    genuinely had no idea what was going on in lectures but read the textbook and you should be fine. ~5 homeworks and not bad, open note/laptop/book midterm and final

    He is one of the best professors in the department! He explains the material very well in his lectures and has a lot of knowledge. You can get a good grade as long as you study.
