Spring 2022 - Professor Gelmini is very energetic and passionate about the content she is teaching. However, sometimes she doesn't understand the student's question well so her interpretation will be slightly different from what you want to know. Also, sometimes the contents on the class are not well organized such that the flow is not very clear, so I have to read the textbook later to make sure I know why it is this way. The grade consists of two parts: Homework and a group presentation about a topic involving GR (chosen from a given list). In general, people get good grades on the presentation and the written report as long as they don't make too much mistakes. So, the homework is very important: there are 5 of them each with about 4 problems. Problems are self-made so you'd better ask the TA for help. Don't worry because there are many OHs available in a week. Thanks our TA Joel, he's super helpful!!
