Hi! I am 20 days prior to submitting and am feeling a bit nervous. The supervisor has returned my draft with comments. In general, he said that although as a narrative the thesis goes well, the analytical parts are a bit problematic but advises that I have no time to address them. According to him, there were significant improvements nonetheless compared to the original chapters and that as it stands, it is at a point where the examiners could ask me to do bits more work before it gets approved. Does this mean that it has a decent chance of getting 'major corrections' (as opposed to a full resubmission)? Have there been outcomes that have turned out slightly better than expected given that a major issue is that the thesis wasn't analytical enough?

I just want to do my best with what's left.

It sounds like it's simply ready to submit and you should do that first.
Then, whilst you are waiting for your Viva start working on the analytical changes he wants.
This will help you get ahead of the game before the Viva and makes it look like you are on top of things.
