I did mine in the days when you could do an approved course in 35 hours - I managed that no problem, but it was full time over about 5 weeks - would have been less but grounded by high pressure haze for a good bit of it, if you want to do it in the minimum you need to be doing it fairly intensively, I would say you want to be aiming for at least 2 hours a day and 2 days/week if you want to achieve this, even better if you can fit in more by taking holiday and doing a week or more in one hit.
