On TESU website : 30-day free trial at Study.com.

[shadowgem]

Does anyone know if TESU and study.com are still offering this 30 day free trial or has this offer expired?

It should still be ongoing for new accounts, but the code increments every month or so. So its higher than 4062 or 4063 now. You could always ping on of them to inquire directly.

Be aware that the Study.com "free trial" options do not allow you to take any exams. You can review the material and take the quizzes but you'll need to pay for a College Accelerator account to gain the ability to take exams.

Thank you Merlin. 

My DH tried this last night while registering a new account. He tried using TESU4063 and kept going up in increments as suggested in earlier posts. He was well past 410+ but nothing seemed to be working. It just kept saying invalid code. He was attempting to register using the direct link on the TESU website. Is there anywhere the current code is actually published that anyone is aware of?  We couldn't find it anywhere on the TESU or study.com websites.
