history: Back in the school, I took an important and difficult subject. But, I studied really well for the exam. When I went in the exam hall, I feel confident, because of prior hard work I never knew what the confidence is. I never felt it before. Until I studied really well for an exam. When I went in the exam hall_comma_ I felt confident the first time in my life. That is great. Yes_comma_ and the most awesome thing_comma_ although I was little nervous_comma_ I confidently gave the exam and secured an A Grade in it.
current: That is great, your studying paid off.
next: Yes indeed! Now I will study in a similar way to be more confident
