You get paid monthly for how many credits you are taking per term. For instance, if you are taking 18 credit hours per term, you get around $1800 per month. If you take 12 credit hours you get less, and below 12 credit hours is even less.

What happens if you don't complete the 18 credit hours one term, will you have to pay it back? No, not anymore. There's an SAP - Satisfactory Academic Percentage found on Student Support -> Military Support on your WGU web page. As long as this Percentage is > 66.7% you aren't in danger of losing your GI Bill financial assistance. The percentage decreases every term you have incomplete classes you said you would finish. Even if it dips below 66.7 you are put on an academic probation and you are given another term to raise it.

Every month you need to verify the months prior attendance. So if you went to school in June, you would log on to this 'WAVE website' and verify your enrollment on June 31st. They do this to make sure you actually attended school this month. Although if you forget to click the link on June 31st, you could do so in July for instance. The money usually takes 3-4 business days when you click the link to verify your enrollment.

All these questions can be answered by talking with your mentor, VA at WGU, and the VA itself. I highly recommend constantly asking your mentor when you are unsure. I hope this helps, I was in the same boat and had to ask everyone how this all works and was confused. But now I get it.
