I was accepted to Waterloo MHI program Feb 6th. I just received an email today from McMaster for an interview for next weekend! Quick question, my acceptance letter from waterloo required me to accept or decline their offer no later then 2 weeks after receiving the admission letter. What did everyone else do who is still waiting to hear back from their other schools? I already accepted as I was happy with attending either school, however now that I received an interview from McMaster I am wondering if I still have options if I were to receive an offer from McMaster. Are there rules to declining once you've already accepted and choosing a different school? Not even sure if I would even consider this, just wondering what my options are incase.
