Hey Julie :)
So I am a Junior here at Temple and let me tell you sophomore year can be hard. The one piece of advice I would give myself if I could do it again is that the teachers are there to help you. I struggled in a lot of my classes sophomore year and only looked to my friends for help. The funny thing about friends is that they are not the ones who are testing you. If you end up struggling like I did, seek out the professor during office hours or schedule other meetings with him/her.
Disclaimer: If you already go to the professor for help in classes, then the comment above is pointless. In this case, my piece of advice is…keep doing you.
