Are you referring to MustUniversity DOT com? Interesting concept and quite affordable. I'm not sure about the academic rigor of being accredited by International Accreditation Organization. Usually universities are accredited by a common accreditation agency within the country of origin. In the US, a regional accrediting agency are the gold standard. In other countries, the country's department of education accredits institution.

Although, I think any learning is always a good step forward, I'm unsure with Must U will be recognized by the company or country you would like to work for. Be careful.

Good luck.
