The email I received says I need to complete the assessment within 2 weeks of receiving the email, but the website says it is open until August. I want to take it again, but have to do the 10 hours of review & wait 24 hours, which basically means the end of the two weeks for me. Can I get more time?
You won’t get your NSO date until you take the test, which is why they probably want you to do the test within 2 weeks. I’d call the NSO office and ask about timetables. It may not be a hard and fast rule.
Since you already took it you should be fine with getting your orientation date. They allow you to do the review and retake it so that you can place into a higher level. Just do it before you go to schedule your courses so you know what level math you can take, if you are going to take math your first semester. The two weeks only applied to taking it the first time. It will be open until August.
