1. In high school, the hardest classes for me was math and chem. Too many thing to remember, lol.
2. I had a good teacher for math class, she was willing to help me catch up where I got behind because of the deaf school I came from did not teach what they should have. She did a lot of one-on-one with me during lunch and free period and after/before school.
If possible, have some time with teacher outside the class is one of the best methods, not just for deaf students but for hearing students.
3. Favorite classes? I don't think I have any, they were all boring. Maybe English in high school and science in middle school.
I was in public school full time the last two years of my high school years. Before that, I was in both school for the deaf and public school. I prefer public school over deaf school any day.
