Ineed the problem dude

Are there options? otherwise, i’d say afghanistan, cyprus, comoros, eritrea, and more are a couple examples of oil-dry countries. let me know if one of those was an option!

It depends on the subject for me. some exams are easier than others so i usually go through it and answer questions i know based on my general knowledge, then double check after. going through the lesson can a lot  because the exams can be  very lesson-specific, but sometimes they are ridiculously long so a lot of people don't take the time. i did find that, when i went through the lessons, i was making 100's on my exams vs strictly using + the internet and  i make 90's.
