I don't understand the 90-day and 180-day access based on the attached image here that says that if you fail you can access the same course again for free. I am/was looking to get the 90-day plus the redo option for an additional 90-day i believe it is. If i get the 180-day access option plus the redo, does that mean i have to sit for the exam twice in 180 days with 30 day in between? ๐ค
