Mosimane was in Morocco last week studying towards attaining Africa's top coaching certificate.
The former Bafana Bafana boss was the only coach from Southern Africa invited by CAF to do the new course.
"It's a different level," Mosimane said.
"It was a tough module for us, more on match analysis and presentation.
"To be honest the job of match analyst is not for us as coaches. We have been spoilt because we have those guys.
"But they said no, when you go to the club where there is no match analyst you need to prepare, you need to present.
"We were taken out of our comfort zone.
"It's a Pro Licence, it's a high level."
Mosimane admits he struggled a bit on his trip to North Africa without his French-speaking friends Aliou Cisse and Florent Ibengé.
Senegal coach Cisse and DR Congo counterpart Ibengé were involved in 2019 African Nations Cup qualifying duty during the FIFA break.
"This time there was only one. My brothers were not there. Cisse was not there, he was with the Senegalese national team.
"Florent had a game against Zimbabwe.
"I had to survive the French language. It was tough, a lot of hours."
