Final year and Masters

So from reading some other threads I got an impression most banks accept final year students for the summer internship (specifically S&T).
Nevertheless since some banks don't; would it be better to write in the CV anyway that I'll be doing a Masters?

- If I do write that I'll be doing a Masters and then don't do it, will I be able to start full-time immediately after the internship or wait a year since I told them I'll be studying for a Masters?

Thanks

Did you ever find out an answer to this?

most do, just apply anyway.
hard to get a IB grad scheme even after your masters without experience in the field
