This is probably the worst Scottish Field crossword for a long time! I have one which I think is right but can't parse and one about which I have no idea at all.
15A PC doesn't need much instruction to work (4) ?I?C - I have DISC as I, S & C are in INSTRUCTION in the right order, but I can't account for the D. Maybe I'm on the wrong track with assuming that PC is a computer rather than "Politically Correct".
5D Work in some bathrooms (4) ?O?L - The obvious answer is POOL but I can't parse it.
Any ideas?
