Hi Stu,
Thanks for the compliments :) if only it was as easy as getting in on the article!

As for your question, yes, medical and police forms do only last 3 months, which in my guessing is why applications only stay in the pool for that length of time (although I could well be wrong on that!)

I believe the medical stuff can be done pretty much as and when you can get an appointment, and the police forms can take however long, depending on the force you apply to! So, sorry thats not much help to you. Could someone who has already applied for their police certificate help? We know you're out there....
