Hi, I am into my 2nd term. I graduated with my ADN last May and started my 1st term last September. I am not sure if the curriculum changed since I began but so far for me it's been good.
You will be assigned a mentor who will be with you from start to finish. My mentor call me each week for bout the 1st 2 months to make sure I was on track and to ask if was running into any problems with anything. The phone calls were never more than 10 minutes long. After she figured out I was good at setting goals and achieving them she would start to set our phone conferences more sparsely like 2-3 weeks at the most.
For each class you will have a course mentor. So every class you will have a person or 2 that you can speak with specifically about the material. I have had to contact a couple during my 2 semester and I have had good experiences with them responding via email as well as setting aside time to speak with me via phone if needed.
Regarding the proctored exams, you will have some. All of the exams I have taken have been straight forward. There is a pre-test that you take at the beginning of the class (most classes) and after taking it you receive a coaching report that details area you did well on and the areas you did poorly on. From that you will know which areas to study so that you can pass the final exam which you self schedule.
WGU sent me a camera that hook up to my computer. At the scheduled test/exam time I log into WGU and click on the button to take the test. The proctor is on the opposite end kinda like Skype and they will ask to have access to your computer remotely for the purpose of making sure you don't have other programs running. They ask you to scan the room and your desk with your camera and also show a photo ID so they can verify your data. Once all is verified you are allowed to take your test. You can't get up to pee or anything while taking the test. I have not had any issues at all taking the proctored tests.
I have 2 of my friends from school who will be starting this summer as well! I hope this helps!
Good Luck with everything!
