No. Some people have to drop out for personal reasons like to work to support their family. Not everyone drops out just because they find the classes to be difficult.
Yeah. Doing exceptionally well at high school requires effort. I got 96.50 in my HSC which basically meant I scored in the top 3.5% of the country for my year
But just passing basically requires just going and writing anything in your exams, no matter how wrong
Who am I to look down on someone when I have my faults too. I have a friend who dropped out because of serious family issues. But I can't stand the ones who drop out & are doing nothing with their lives.
