Hang in there!
a competition with each other to see who comes first.
Education is not a competition with each other to see who comes first. It is a competition with yourself to see whether or not you make the cut, if you are learning or not, if you are moving on or just slacking.
Forget about competing with others. Compete with yourself. If your grade is failing yesterday, aim for a passing mark today. If you get a passing mark, aim for excellent one. Always aim to be better than yourself yesterday and not better than anyone else.
Millions of students, and now professionals or even retired from their profession, have gone through the challenges like you're going through but they made it. Some may have quit and who knows where they are. To your point, many people can become entrepreneurs without graduating from school. But that does not mean they did not learn somewhere. They just took a different path to learn. Academic learning will still be helpful in whatever career you choose.
I came across your blog through @stever82's post as he featured your blog. When you are done with your exams, maybe you can also join us in the contest. 😊
Good luck on your exams.
