With the 18/R and 18/W courses, Phil Barnes has agreed to hold a third 1.8 day FD4 course (with the same content and format as 18/R and 18/W). This course, 18/Z is on 1-2 August 2018. Because of Phil’s heavy FD4 course commitments, Peter Gray will be tutoring (instead of Phil) the 18/N FD3 course on 4-5 July 2018.
