    PHYS133 . Martin C L 9 Months Ago

    She's a really nice professor! The homeworks are usually super easy, but she always answers emails really quickly and makes herself available for office hours. Her lectures are really in depth too and she gives lots of examples.

    PHYS133 . Martin C L 3 Years Ago

    Dr. Martin is very friendly and genuinely wants you to learn the material. Homework for this class was really difficult for me, but her office hours are a live saver. Usually there are 7-15 students that go to her office hours and we all work through the difficult problems together. The exams are tough, but the class is curved!

    PHYS132 . Martin C L 4 Years Ago

    Great Professor. Don't know why she doesn't have a higher rating. Moderate difficulty for an upper division physics class. Readings are usually 1-2 chapters a week but her notes are very thorough. She is very nice in office hours, answered all my questions. HW's are hard, Midterm is easy, final is a little harder but fair.

    PHYS133 . Martin C L 5 Years Ago

    Very rude professor that doesn't care to help students if they reach out. Class is test heavy

    ASTRO1 . Martin C L 6 Years Ago

    Great class to take if you like a challenge. Came in having never taken a physics class before (and yes, this is a physics class) and managed to grind through it. Martin is very knowledgeable about the subject and is always willing to help you understand the dense material. Not easy, but very rewarding.
