The 2019 Weekly Exam Series (now the PE Prep Series) has "on-demand" exams open. If you're interested (it is extremely early to begin studying), you can take the on-demand exams at any time.
To access any exam, just go here:
Scroll down to "Access Exams" & select your exam. Only the "On-Demand" link is currently active. The first week of the 20-week series will start in June.
Any questions, please don't hesitate to let me know at email@example.com. Thanks!
