Beginner's Italian course -for english speaker - download size help


I really need to know how many MB in size a course is before I download it. I can’t find this information anywhere - not in a download window, information about the course - nowhere. IT’s importatnt because I’ve started doing the Memrise Italian 1 course. I download them to my phone and use them offline as I don’t have much data - (and wifi is not everywhere here). I downloaded Italian 1. I wasn’t able to download Italian 2 over wifi. I’ve finished Italian 1 and want to keep going. Please help!
