Letter of Recommendation

Hello CC community,
As I am planning to apply to MIT this year (coming from the UK), I understand that I require two letters from a science teacher and a humanities teacher. However, because I am doing A-levels in sciences and maths, I am unable to have a humanities letter. I know everything’s fine and MIT understands this but my maths teacher claimed he completed all forms (Evaluation B) about four days ago but after refreshing my page, it still says that nothing happened.
My question: Should I contact MIT and ask them if there was some sort of misunderstanding or should I resend the from to my teacher? Thanks in advance.
