Quality Exam Prep Shouldn't Cost Hundreds
I'm Ran Chen, an engineer with 20+ years of coding experience. I passed my Life Insurance license, EA exam, SIE, Series 6, 63, 65, and finally the CFP® exam.
Through all these exams, one thing became clear: exam prep is expensive. But with AI, we can change that. Quality preparation can now be free for everyone.
What's Next After the AFO?
After passing the AFO, you can pursue these career paths
Aquatic Facility Operator
Operate municipal, park-district, school, YMCA, military, or commercial pools: test and treat water, run circulation and filtration, and keep daily logs that health inspectors review.
Aquatics Manager or Coordinator
Supervise operators and lifeguard staff, own the emergency action plan, chemical-delivery contracts, and seasonal opening/closing for a parks-and-recreation aquatics program.
Pool Maintenance Supervisor
Lead mechanical-room work: pump and filter service, heater and feeder repairs, and replacement purchasing for hotels, apartments, or multi-site commercial routes.
