"Just thought you'd like to know that Max, who attended your Easter week's French revision course turned a 'U' grade mock AS into a 'B' grade in the actual AS. He'd lost confidence in his French, chiefly by not having grasped some of the basics. The tutoring you provided allowed him to ask the stupid questions without embarrassment and cover his knowledge gaps. When he got back to school he was firing on all cylinders. Please can you pass on the terrific result to his tutor. Thank you and we will no doubt be seeing you again at Easter."
(Mrs D, Buckingham)
