To send or not to send

Hello! I got my subject test scores back today along with everyone else and I am very happy with my scores! Only on one am I wondering whether I should sent it or not. On Math I I got a 740, which is by no means a poor score. However, I am a senior and have taken calculus so I should have taken the Math II. I did not because I knew I would do poorly as I never really understood the concepts and they left my brain immediately after I was done with the course. Does a 740 on Math I look bad to selective colleges? All my applications except one (which wants to see 3) wants to see 2 subject tests. Should I send all 3 tests or my tests besides Math I?
