Sorry - but I disagree with screwing up everyone else's circuit just because one student can't cope. Go and practise 'circuits at height' elsewhere if you must, but don't let the student get away with flying wide circuits just because he/she can't cope with trying to do too much too soon. Build them up slowly at a pace with which they can cope, but within a standard circuit. That's how the military do it - and they invented flying training methodology!!
