On-Demand VCP training

I'm considering undertaking a VCP path (DCV or DTM) but can't afford to take a week off work to attend the classroom course in order to qualify for the cert.

2 questions -

1. Is the on demand training worth the expense (it seems to be the same cost as classroom based, but obvs 30 days vs 5 days to absorb the training may be more effective), any opinions on this?

2. I need to pass the Foundations exam before the VCP exam, will the training equip me for both exams and is it possible to pass foundations without attending a training?

Thanks

Dave
