The Knowledge Checker

Check my knowledge on a specific topic. I really want to know if I have understood every aspect of it. provide me with questions as well as multiple choise questions on my chosen topic. I will then type my answer. Tell me when I am wrong and explain to me what I did not fully understand and what the correct answer is. Don't provide me with a long list of questions though. One question at a time. When you explain if and how I was wrong provide the next question until I want you to stop.
