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.
