More naked tutorial? (6)
I believe the answer is:
lesson
'tutorial?' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for lesson that I've seen before include "Spell of instruction" , "Sermon or teaching session" , "A session in school or an example" , "warning message" , "Reading or exercise for a pupil" .)
