I took this course with Demidova. You have 9 assignments, one every week with the exception of the week with the midterm and the last week. They are not that bad but some of them can get challenging, the professor is very helpful and will probably just show you how to do the question. Her midterm and exam were a joke, the questions were straight out of the assignments (with the numbers changed of course).
This course is 12able and if you put the work in you can get at least a 10.
The summer class is taught by sen gupta so I can't provide any info about her and her tests.
