College was more difficult than HS for me because:
1. I skated through HS. The courses were easy, I was never academically challenged, except for algebra
2. College had fewer graded assignments. Some classes had only a midterm and a final, each counting for 50% of my grade. That was a lot of pressure! And not knowing the professor's testing style added to it. Were they testing over lecture, readings, or both?
3. Nobody stood over my shoulder. While I considered myself a good student in HS, when I got to college, attendance was not required. Wow! So, do I want to hang out with my friends on the quad and enjoy the beautiful spring weather, or, go to class?
4. HS tests often wanted me to regurgitate knowledge. College exams asked me to apply it.
5. It took the first semester, and part of the second, to get adjusted. I didn't have older friends or family to guide me, and there was no internet. . .
6. I had to make my own schedule - choose the classes, what times they met, the professors, etc.
7. Money management - all of a sudden, I was spending a lot more money than I'd ever seen in my life!
8. They wanted me to actually WRITE in my books. Sorry, I had been brought up to respect books. . .
All that being said, by the second year I was doing fine. So, if you need help along the way, ask for it! Take advantage of writing labs and other resources offered by the school. It all comes together. Remember to have some fun while your at it!
Keep pushing through and doing your best. You got this!
All that said, college is one of the funnest times and hardest. Really lean into it to make the most of it and enjoy it.
If you are finding that college is posing difficulties for you it may be because of the new challenges you are being presented with. College is a different experience for everyone and it depends on how enthusiastic you were about being a student prior to enrolling in college. Another factor is understanding your purpose and intent in choosing to go to college. Beyond obtaining a "good job", what are your personal goals ?
Being a college student is a new and grand step in life and if you are willing to make the stretch, it can be the best years of your life. College teaches you about yourself, about others and how to communicate. But you have to be willing. If the information load of courses has you flustered, take it a bit slower with less courses per semester and go for a course or two during summer session.
So the answer is, college is not difficult for some and difficult for others but only you can examine what is happening and know why. Just like anything else in life, when things get rough, pace yourself and even if you need a major change in your school experience, try that. An academic, on site path may not be for you, but test it, finish what you've started and see how you feel then. Create a balance of study, practical requirements, work and recreation and entertainment.
I hope that this helps. We will all encounter difficulties in life even after college but the important thing is what you do about it. Best wishes to you !
