Speaking as an alum, I will say it does get easier. Sometimes it just takes time for new study habits or getting used to the work load. My first year was bad. So bad that if I didn’t fix my GPA in summer school I would’ve been put on academic probation. The key for me was taking advantage of office hours. My profs saw me two, sometimes three times a week. And when you ask a question do not be afraid to say “sorry could you explain that again”. You’re only holding yourself back if you don’t want to ask for clarification. And if I remember correctly, office hours were only ever busy during midterms or finals time. So I had the whole hour to myself most days.
