I know people who went to the academy (physically in OKC even!) with zero aviation/air traffic knowledge and they worked hard to catch up to where others were. 8.5 hour classroom days, and 3-4 hours of nighttime reading to ensure they understood the material. They only relaxed on the weekends and not even much then.
This isn’t a McDonald’s job. If you can’t handle the workload, then you’re gonna have an even tougher time training at a facility. The academy isn’t there to hold your hand and the facility you wash from won’t be there to teach you fundamentals either. Self-motivate or resign now and save the taxpayers some money.
