hani cevabı uzun sürecek olan

okula giriş-çıkış saatleri

sana soru sormuştum - i asked you a question

hatırlıyor musun - do you remember?

hani cevabı uzun sürecek olan - it will be a long answer )i think)

okula giriş-çıkış saatleri - times you go to-leave school

The other translation is also good. oceanmavi you are doing well.

"I had asked you a question, do you remember? It was the one which would have taken to much time to answer. The one about the entry and exit times of school."

Could a native speaker tell me if it's OK to use entry and exit in this context.
