Bio extra classes after AS exams

hey guys the new time table is out. Miss Durga had requested to have extra 2 hours of classes for bio per week. Fyi, we will be having 6 hours of lessons for each subject. But since Miss Durga requested , we will be having 8 hours of bio each week. Is either we stay back an hour after our lessons which is 5-6pm after LAN classes or we have it on a saturday and it's 4 hours straight. Please reply this post as I need to inform ASAP. if you guys don't response, then we might end up getting bad time table arrangement. So I do hope you guys please response to this. THANX A BUNCH
