My DS is sitting the Eton CEM list test soon. Does anyone know of any tutoring agency that might have a really good simulation of the Eton test, including adaptive questions and with the same sorts of time limits and inability to go back to previous questions? My guess would be that the larger agencies might because of how many of their clients have children applying to Eton and other schools with these CEM tests have built an in-house solution designed to help students get as familiar as possible with this type of test.
