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?
