I'm looking for a professional to write 60 original multipul choice questions + answers (they can't be copied from anywhere, you must think of them all by yourself).
The questions should be of varying difficulty (15 each of Easy, Intermediate, Advanced, and Expert difficulties). Additionally, you'll need to provide a URL source that proves that the correct answer is indeed accurate and what exactly the MCQ checking.
