Hello, I'm creating a simple Online Exam System but i'm having some problem with my codes. I want to count all the correct answers and wrong answers. How should I do it? I mean, what code should I use? I'm a beginner in jsp. Please help. Thank you so much.

my advice: you seem to know the basics of jsp, no head over to servlets.
that should get all of that java code out of the jsp file, and make it a lot easier to work with.

Oh thank you for that sir, But I just wanna ask what should I use because in that code that I'm doing it only checks 1 by 1. Maybe theres a code to check all at once but idk what should I use.

they're all different components, so I don't see how you would put a 'check all' in there, without writing a check all method that checks them one by one
