A quick tour
A quick tour of the 11+ Masterclass: finding a topic, watching a lesson and taking the check.
Three steps to every lesson
-
01
Watch
A short, focused video teaches one skill with a worked CSSE-style example — easy to fit in after school.
-
02
Read the summary
A one-page summary sheet sums up the key ideas, a worked example and the common slips to watch out for.
-
03
Pass the check
A 5-question check confirms it has sunk in. 4 or more is a pass; otherwise your child can rewatch and try again.
