U can apply am class when u pay the reservation fee. I believe there will be am vacancies release sooner or later. Call the school regularly to show your sincerity and yoyour application will be concerned!
We went for an interview yesterday, and we all appreciate school arrangements , there were not only having an interview but also having a story telling by NET teachers.
The only one thing made me disappointed was there were no more AM vacancy already but actually my little did a good job in the interview.
Anyway, St. N. really a nice school as i found.
