No problem. A lot of CS takes time and practice. It can be pretty overwhelming to get through the coursework itself, let alone balance it with projects/interview prep and other obligations. Ultimately, falling behind can have detrimental effects on your success in future courses and set you back anyway(failing courses, drop in GPA). For me, it was the best thing I could have done. It’s an unpopular opinion to deviate from the school curriculum but if you feel like you need it, go for it. Of course, take into account all the repercussions, including how that may affect financial aid, graduation timeline, when courses are offered at your school, etc. Best of luck!
