TESU Computer science process question

[emmaya]

Hi rachel83az , thank you for the advice , can I ask the question relate with question 4 's answer ? 
4. No. Don't pay tuition until you are actually going to take classes. You don't need to take most classes at TESU. It should probably be the very last thing you do at TESU, not one of the first. 

So, I don't need to enroll in TESU's July Term to take courses. First, I will list the credits I need to complete according to the roadmap, and I would appreciate everyone's guidance on that. Then, I can study the courses on Sofia.com and Study.com at my own pace and complete them. Afterward, I can transfer the credits earned from those courses to TESU. Finally, I will fulfill the remaining credits required by TESU. Therefore, at this point, I don't need to make any payments for a flat rate or per credit to TESU. I just need to finish the listed courses as soon as possible on Sofia and Study.com and transfer the credits to TESU. Is my understanding correct? Also, I don't need to enroll in courses at TESU for now. I will assess the credits after completing each course and then transfer them to TESU. Is this understanding correct?
Please view the attachement . Thanks !!~

Yes, exactly right.

One thing I will mention, however, is that you'll want to PAY FOR (but not take) the 1-credit Medical Terminology TECEP every 12-14 months. Including right now. This only costs $52 but will unlock full enrollment status. Full enrollment status unlocks unlimited evaluation of transcripts from Study.com, Sophia, etc. Being able to send in your transcripts every month or two is crucial to confirming that you're on the right track. It also "locks in" your already-completed classes. If TESU were to suddenly stop taking a class already on your transcript, you'd be grandfathered in and it'd be okay. If they decided to stop taking it, but you hadn't transferred it in yet, you'd be out of luck.

Aww, I only need to register for this course; I do not need to attend this course every 12~14 months, and I also do not need an exam to gain this credit. Is my understanding correct? Can you help clarify if this is the course? Please view the link and screenshots. Thanks a lot! ~

Regarding books, how does everyone find books? I know BookFinder.com and App Libby. Does anyone have good advice? ~
