Yeah, it is, but it’s also worth it. If you put in enough time and always ask when you don’t understand something then you can get through it. Life has a habit of getting in the way at that time of your life, though.
Yes very hard. I wasn’t happy at the college I went to, and I didn’t know what I wanted to do afterwards, but I stuck with it to keep my options open and I’m so glad I did! Plenty of people dropped out of college and really narrowed down what they could do instead.
