Hi everybody. I experienced a distinctive sharp pain in my sternum after I completed my set in weighted dips. At that time I would say the pain was a 7.5/10.

The pain slowly decreased over the course of a week and I think it's more or less healed now. At rest or normal daily actions there is no pain. I experience a mild 1-2/10 pain only when I put my chest in a hyper extended position by bending back. It pains at the bony hard circular part at the center part above upper chest (is there where costocondritis occurs? Right after my injury the pain was more widespread across sternum and ribcage).

I am wondering if I should rest for few more days till I'm 100% pain free before resuming my gym exercises. Is there anything that I need to keep in mind to prevent reinjury? I'm never going to do weighted dips again. I'm wondering if I should skip muscle ups as well.

This is the most frustrating course for me so far. They introduced a new change this Semester (Summer 2026) that the Case Assignments also must be done independently in addition to the Homework Assignments (previously, the Case Assignments were compulsorily a team project).

The Case Assignments are so time consuming with literally hundreds of inter-related excel formulas that if you make a typo in one cell it'll trigger a chain reaction and throw your values off everywhere.

There is minimal learning or understanding involved, just copy-paste the same/similar formulas shown in the lecture videos over and over. Just strenuous manual work. At this point I have less motivation to understand and appreciate the material, I just want to complete all the assignments and be done with it.

I took this course for an "easy" summer course to pair with the AI course, but I am spending far more time on these assignments than those in the AI course lmao.

The current NOSI version for the Summer 2026 semester is quite matured now and does not cause any hinderance with normal development practices. It's a very good course, don't let NOSI stop you from taking it.
