How fast can I give the exam?

0 Preparation at the moment, 0 professional work ex but studied finance purely out of interest through my life.

I gave the Kaplan diagnostic mock today (level 1) for the first time with no prep and I had 70% accuracy for the diagnostic.

Not sure what to base this against, since I don’t know about the difficulty standard. Should I register for the February exam, how long will it take for me to prepare for it?

Thank you
