Are you living on or off campus ? If you’re not living in dorms I would make a conscious effort to be active in student life activities or find some club to be apart of so you meet people outside of your classes. It can be really easy to not go when you live off campus but make sure you force yourself to get involved, you’re experience will only benefit in the long run. As far as the studying, just be organized. My planner sets 3 weekly goals and 3 daily ones and that helps me stay on top of things so they don’t pile up. Also, do the readings in the textbook or other sources. I’ve watched so many people wracking their brain trying to study what they learnt in the lecture for hours when they could have spent a faction of time reading the damn textbook or watching the video the prof set and understanding it. I do my best when I sit down with the readings as well as the notes I took in class and combine them into one big great note. Hope this helps ! Don’t forget to make time to have fun and get involved, a good planner will help you see you have time for it on top of studying !
