Question

I urgently need you to check these sentences. Thank you very much.

1) I received the address of your school from a university student I met during my summer vacation in Madrid.
2) We are currently looking for a school interested in joining us in a multilateral Comenius project.
3) We'd also like to know if you would be interested in a long-term mail partnership which could eventually lead to a student's exchange (between our schools).

Answer 1

1 and 2 are fine.

I'm not sure what you mean by "mail partnership" or "student's exchange." Let me know, and then I can tell if you need slight or major revisions.
