    Research methods
    Dear Charlotte There is no distinction between SL and HL for which research methods that they need to know. However, Paper 3 - the unseen passage - is only for HL candidates. They will have to be able to answer questions about a quantitative...

    LP 3: Memory and neurotransmission
    Sorry, one more question: if the SAQ is: Explain the role of one agonist with reference to one study, what agonist and what study should you use? It's written above acetylcholine, but how is that an agonist? Thanks
