Thanks in advance for your replies. I'm trying to help a friend after learning about this great community and degree approach. My friend has a lot of industry certifications(IT/Tehch/Comptia/AWS/etc) and PUG looks like a great option for him but he has no college credits. 

Also, I had a few more questions about PUG's excel track:

1. What would be the fastest and best route to knock out the previous 3 college course requirement?
   
2. The 180 credit requirement is throwing me off a bit. How many credits are each class? There website says "Take as many 1-credit courses as you want in a term and pay one flat tuition rate". If some classes are more than 1 credit, do they not apply towards that quote?
   
3. Is it really unlimited classes per term?
   
4. I assume the finals are proctored. Are there additional fees for that?
   
5. If you can take unlimited classes, does anyone have experience completed two degrees relatively easy?
   
6. Anyone have any complaints about PUG's excel track?
   
7. The excel track degrees at PUG are very concentrated as compared to TESU's more broad technology degrees. It may be more money and TESU may not transfer some of the certs for credit from places like W3C but would their degrees be a better option if cost for each program was an irrelevant variable and you just wanted the degree with the better job prospects?
   

Again, thanks in advance  for the replies.
