CT3 is being split into two examinations, one will be a 3 hours written test, and other will be a computer R programming test of 1 hour 45 minutes. You can refer to the curriculum changes here: https://www.actuaries.org.uk/studying/curriculum-2019 Hope this helps. Regards, Shyam
Slayedit is correct - the material is undergoing a complete overhaul. CT3 will lose some of the earlier work (chapters 1-3) which will become assumed knowledge. Gain some CT6 (Bayesian estimation and GLMs) and some totally new topic (eg PCA and non-parametric tests).
