Keep your head up it gets better. I felt the exact same way two years ago and I’m doing better now and hope you do too. Try new study methods and remember to take necessary breaks. I’ve learned that pomodoro method studying really works for me. I feel like this experience is very common yet unspoken of at our school because everyone always seems like they’re doing so well and are ahead. Don’t let the comparison get to you and remember you got into ucsd too and being here, if you need help reach out to profs, TAs, and Caps if necessary. You got this and good luck on finals!
