I am assured that this is BRILLIANT. but it won't work on Macs!
An excellent learning tool with 5 levels of difficulty.
Highly recommended and very well organised.
For Mac iPad or iPhone
A superb site for testing your play - ALL levels
A BRILLIANT site for serious players/learners
More learning with Acol
Foundation level Acol from the English Bridge Union
Good site with loads of conventions
