FREE graduate classes this spring!

[NotJoeBiden]

Am I mathing this correctly if I was only looking at the grad school courses? 

For M.S. in Agricultural Sciences, M.S. in Agricultural Leadership, Education and Communications
3 Credit hour (Free via 2025 winter Mini) + 3 Courses (Estimated $2709 for out of state, $1485 for in state) + 6 Credit hours (free via 2025 winter additional course) 
= $225.75 per credit hour for out of state and $123.75 for in state.

For M.S. in Business Analytics and M.S. in Marketing & Marketing Analytics
3 Credit hour (Free via 2025 winter Mini) + 6 Courses (Estimated $4,988 for out of state, $2,540 for in state) + 3 Credit hours (free via 2025 winter additional course) 
= $415.67 per credit hour for out of state and $211.67 for in state.

For M.S. in Computer Science
3 Credit hour (Free via 2025 winter Mini) + 6 Courses (Estimated $5,026 for out of state, $2,578 for in state) + 3 Credit hours (free via 2025 winter additional course) 
= $418.83 per credit hour for out of state and $214.83 for in state.
I don't think these masters have a free course in 2025 Winter mini so I think the CS tuition would apply: M.S. in Artificial Intelligence, M.S. in Biological Sciences, M.S. in Chemistry, M.S. in Technology Management, M.S. in Mathematics, or M.S./M.A. in Physics.

The normal out of state graduate credit hour seems to be around ~$800 per credit hour (why is there not a set cost per credit hour?). This would make the cost to complete the other 18 credits an additional ~$14k+ depending on the masters... That is much more pricey than what I expected.

There is a cost per credit hour. 

Texas residents pay $758 a credit hour; non-resident is $1,161/hr. This is one of the most affordable grad schools out there. The College of Business is a little higher at $783/hour for Texans and $1,191 for non-Texans.

You can also qualify for a variety of grants/scholarships depending on your situation; scholarship portal will update in December. 
You can qualify for in-state rates if you secure an assistantship OR at least $1,000 in scholarships.
Here is the cost calculator; move the bar to 1 hour. Online classes have an additional fee as seen on the calculator.  

You can find the number of credit hours for your program below (use with the calculator):

• M.S. in Agricultural Sciences
  
• M.S. in Agricultural Leadership, Education and Communications
  
• M.S. in Business Analytics
  
• M.S. in Marketing & Marketing Analytics
  
• M.S. in Computer Science
  
• M.S. in Artificial Intelligence
  

ETAMU is not the most affordable grad school out there by any means. It is actually very expensive. For example, graduate tuition for the Cal State System is $368/credit hour for residents and $788 for non-residents for graduate programs. Heck, Harvard Extension School charges $835 a credit hour for graduate programs regardless of status.
