Here's an advice:
If you're struggling in high school, don't even think about going to college.
Honestly, the things that you learn in high school are child's play when compared to the amount of shit you'll receive in college. Let's get the logic here.
Talented High School Student = No studying and getting straight As
In college, this student will have to work his ass off to maintain his 4.0 GPA
Average High School Student = No studying and pulling off a pathetic 2.5 GPA
How do you expect him to survive if even the talented high school student is struggling a lot in college?
Remember, children, college is only for the gifted.
