Hi,
I am a new user. It's very very very helpful. I just found it last week. I plan to take the SAS base exam next month, so I want to know if the validating day is 180 days for this link. What's the last day?
I read about three sessions everyday, and I wish I can pass it.
I got to know this forum one week before my SAS base exame. The online document is so helpful. I'm sure that I won't get so good a score without this material.
