Hi,
Some university’s can take a while to get back you, it really varies across university’s. I had an offer for my masters within 2 weeks, but I applied mid August, only a few weeks before the term started.
If your concerned and wanted to check on your applications, I would recommend contacting the individual university’s. They may be able to give more details, such as a timeframe.
Good luck with your applications!
