How long do the exemptions last ?

Hello,

My name is Kay, I’m from France and I’ve a bachelor’s degree passed in 2012 which provides me exemptions for papers from F1 to F9.

I’ve seen that in order to claim for the exemptions, the degree which provides you those exemptions must have been passed for less than 5 years ago.

Does it mean, if I suscribe today and claim for exemptions for F1 to F9, I will have to pass the five others papers before 2017 ? If not, will I loose my exemptions ?

Thank you advance, and please forgive my grammaticals mistakes.
