This is similar to the School Leaver programmes run by large accounting firms in the UK as well. You get paid a decent amount to get accredited whilst working for the firm. The programmes could take 6 years, but at the end of it, you would be a much more valuable employee than the person who drank away 3 years of their life! Plus you'd be a qualified accountant!
The downside is when all your mates are out having fun, you're being worked to the bone! Not really fun for an 18 year old.
