1a) When you finally solve a question that stumped you for minutes.
1b) When you cant solve the question or don't understand that particular topic. I will seek for help from the teachers and try to work it out.
2a) Fun and interesting.
2b) By sharing what you know and helping each other understand the question or topic.
3) If I don't get it, I will ask the teacher how to do it until I get it. I collect notes as well. For example, if there is a particular method that I find useful or failed to do it before, I will jot down the question onto a notebook and write down the reason why I add or multiplied that.
