Medium of Instruction letter (non English-speaking country)

hello, i think i messed up majorly by assuming the ECCTIS process would be straightforward and didn’t expect a letter from my university to be required.

How have people gotten on with getting an MoL delivered from non-English speaking countries, especially France? Was it from the admin department or something else?

I’m afraid I won’t be able to get one due to the summer holidays and I’m worried it’s over for me! My degree was taught mainly English by the way.
