I used to be an instructor at ABI, beginning when Bill Pearson ran the place. Yes, the student's drive matters. If you're willing to work at it, you've got a chance. But the downfall for ABI, to me, was the new ownership.
When Bill ran the school, he'd screen applicants to make sure they had a chance. If their talent level was severely lacking, he'd have the spine, and the decency, to tell them. Under the new ABI ownership, the interview process consisted of determining whether your check would clear.
The number of students who had absolutely no talent was alarming and a great hinderance as an instructor. I fould myself having to decide whether to try and help the student who was far behind the rest of the class, or help the other students and, basically, let the unqualified student flounder. As time went on, there were more and more of those students who clearly could not figure it out. But, they had money so they remained.
I don't know anything about the "new" ABI, but I hope the screening process is more than a credit check.
