clearly never taught a class before, gave reading quiz 2 days before midterm, midterm wasn't graded until 5 days before final exam (too late to drop w a W), would ghost emails, homework and exam with many typos, if you asked abt hw they would not even answer ur question & made u start from top on board, came to midterm late unstapled and with typosPHYS2303 2024-12-18 15:04:24 +0000 UTC
This was clearly their first semester teaching. Exams were too long for the time given, lectures were sometimes unrelated to what we needed to understand, and course expectations were not always clear. However, they clearly cared about the class and students, were super helpful in office hours, etc. I expect they will be better in future semesters.PHYS2303 2024-12-17 13:34:41 +0000 UTC
