    Hey! Just wondered which of you fellow year 11s took that B123 (OCR 21st Century Science) test today and which questions you struggled on/ found really easy!
    I though that it was luck that there was no question on ADH, but I wasn't sure of I wrote the write thing on the nitrogen cycle question:confused:
