I couldn’t continue my daily updates lately because I was busy with final papers, seminars, selecting research topic, & important interview - all of it was taking most of my time 😭

Things have been really hectic, but I’ll start posting regularly again from next week.

https://t.co/HO9HZ1gu7y is supposed to be research-oriented but sometimes the assignments still feel like undergrad😅
Just a random thought from 2nd sem
is it always like this or does it get more research-focused later?
