After quiz you can send them on Locker from some CPA, you sucesfully completed quiz, now you are qualified to win iPhone or something like that.
Best way is to make a website for an IQ test, and then at the end of the test (I said IQ because that takes a little longer so they will probably complete the offer), put one of these
1. Share on social media for result (more traffic, not much monetization)
2. They send an SMS that costs 0.50$, and you get a result. This is very good.
3. COMBINE THESE TWO, This is the best, and I know a guy who does this, and he earns a lot. Basically you get traffic+money.
