Reflections & Notes:
-> Julie & Lynn finished all planned implementation
-> Yuki had to change feature midway given discoveries about the instructors tag (dependency criteria), leaving 2.5 days to implement polls feature. She got frontend to show up, and the progress is on-track to be finished by 5 days before sprint 2 deadline.
-> Doris encountered difficulties reading through the codebase and understanding the logic behind adding reactions feature. Implementation deadlines pushed back to sprint 2 checkpoint 2 (Saturday, Feb. 15).
