Deadline to enrol for BP


Hi, I Am new here, i was wondering if once approved by the APHRA and is eligible to study the BP, do I have to enrol myself straight away? Or do they give a deadline for you to enrol and do the BP at a certain period? I am planning to submit my requirements ASAP as the 5years requirement that i have is only until this year and but i would like to enrol for BP by next year as I am still saving up. Please help thanks :yes:
