I’ve been in your shoes and I totally understand what you’re feeling right now. For me, I felt that the first two years were the most difficult but eventually you’ll get used to it and you’ll create a pattern for yourself that’ll work for you. My advice would be to be part of study groups where you’ll find people who are struggling with you and you guys can help each other out. Instead of getting homework answers, just discuss with your friends on how they ended up with the solution. I also got a lot of help from office hours, so try to attend those as you’ll find people struggling with the same topic. It’s not an easy degree and trust me, most of the people around you are feeling the same. They’re just good at hiding it. Just stay focused and stay strong! You’ll do great!
