I'm a bit of a crossword newbie and I'm struggling with the final four clues in the top right-hand corner. Could someone help me with
11a Just starting, son is required to give address to teacher (3). I was thinking of due, fit or apt but cannot parse it!
14a Turns off gas, as one does in kitchen after meal? (5,2), I have D-I--/-- for this but cannot make any sense of it.
Thanks.
