We got hit hard on Monday. 85 quick registrations and counting, in the end we had to topic approve to stop the spam and adjust some Cloudflare options.

Keep in mind that there are human spammers as well who do research and work for bots. By supplying answers to 3/4 of these questions in the question itself, you're making their lives very easy. These questions, in general, are rather easy and your target niche don't need those answers in question. If these questions are old, it may be well that the bots/humans have discovered these answers.
You'll also want to switch to hCAPTCHA and ensure you have "Difficult" set for the passing method if you continue to get hit hard.
Be sure to also flag all these users as spammers as that will tell our Spam Defense of them.

Under the Price section, you need to tick the 'Renews?' option.  Once that's on, you'll have the option to set renewal prices and how often.  You'd type in 1 and change the drop down to 'years' to have it set to allow members to renew once a year.

Would there be a way to use this similar to a LMS (Learning management system) where you have several repetitions of:
Ungraded pre-test Content Quiz Then a final test (maybe the score weighted more)
All the quiz and test grades accumulate to a overall score?
