I did cheat sheets for all the possible constellation of signs I could think that may come up during a PACES exam. I mentioned in my PACES Exam Guide Series (Part 1) that best advise I received at the time I was revising was that “You don’t have time to think during the exam, So have your differentials ready at the tip of your tongue.” So I invested a fair bit of time doing pattern recognition – if “these” signs turn up the differentials are likely to be “this list”. And have this ready. So when you get a unilateral pure motor neurone patterns of weakness in the real deal, you have in impressive list ready to blurt out to the examiner. You sound more organised, systematic, confident if you have this but of knowledge under your belt so you focus your energy in PACES on how you come across rather than remembering what diagnoses can be at play here. And it worked – I attribute so much of my PACES Success where I scored 168/172 on the first attempt to this. So, thank you Registrar!
