Sort of teaching aid maybe as usual I avoid messing up (5-6)

Ross

I believe the answer is:

audio-visual

'sort of teaching aid maybe' is the definition.
(a teacher might use audio-visual aids)

'usual i avoid messing up' is the wordplay.
'messing up' indicates an anagram (I've seen 'messed up' mean this).
'usual'+'i'+'avoid'='usualiavoid'
'usualiavoid' with letters rearranged gives 'AUDIO-VISUAL'.

'as' acts as a link.

(Another definition for audio-visual that I've seen is " Using sight and sound".)

I've seen this clue in The Times.
