Sheble is garbage. It's well known, well established, and with good reason. That only reflects on you if you were part of the problem but it sounds like you weren't. Glad there are those that cared, but the culture there was terrible.
Are they even still in business?
I went to Sheble in 2002. I knew before going to Sheble it was a place to get a checkride done, not a place to learn a certificate. It was the best accelerated program I ever went to. I guess 2002 was a long time ago though; things do chance quickly at flight schools.
