I'm reaching out to inquire about the tuition fees for different grade levels, specifically grades 5, 6, 9, and 10. Could you provide me with the pricing details for each of these grades? Additionally, I would like to know if there are still available spots for registration in these grades, as I'm considering enrollment options for my child. It would be great if you could share any relevant information regarding the registration process or deadlines as well. Furthermore, if there are different fee structures based on program types or additional costs I should be aware of, please include that too. I'm looking for a comprehensive overview to help me make an informed decision. Your prompt response would be appreciated as I am eager to understand the possibilities for my child's education. Thank you!
