Using the same personal statementWatch
I would also advise that you at least slightly adjust/tweak it. Maybe add in things you did in your gap year and how it's helped you.
So basically, you can use your PS exactly the same if you want. You can tweak. Edit. etc.
Obviously, you should be changing it quite a bit if that was the reason you didn't get interviews in the last cycle! And anyway, you want to be including gap year information too
