DOB was brilliant he was my tutor for two years great lad threw me out once but still you have to love him
sound and always up for a laugh. loses control thouh too much to the detriment of the learning environment
David has a outstanding knowledge of his subject and makes his classes interesting and enjoyable. Downside - but tends to lose control class, effect the whole learning environment.
I am a past student and Mr. O'Brien was one of the best teachers there, always looked forward to his class, he made maths interesting!
best I.T. teacher of all time.his brilliant 'close the programme and log off' phrase will always echo through the walls of S7
