Univesidad Abierta y a Distancia de Mexico UNADM

[Avidreader]

Yes, yet another option for people with a very tight budget that speak fluent Spanish and want a college degree.

The UNADM is extremely popular in Mexico because it is 100% free (so expect fierce competition for sign ups), and probably the most talked about public online university in Mexico alongside the UVEG.
The degree offerings are still a bit sparse (but given its popularity, I expect them to add more degrees in the future). Sign ups are usually once a year around late July (classes start every October) and you can't accelerate degrees like in the UVEG. Students mention the degrees demand a lot of time, classes tend to be synchronized in variable schedules, which makes the school a difficult option for people with jobs.

For people without time constraints and don't mind taking 4 years to get their degree instead of a bit less than 3, the free price tag will be worth it.

This school forcibly demands a QR code Mexican CURP number in digital format along with a scanned copy of the highschool degree. It seems like the school doesn't cater to foreigners, so I don't know if they accept foreign ID numbers in liew of the CURP and Spanish translations of highschool degrees.
