I had her for French (5 years) and she was without doubt the worst teacher I had in the school. She was very dis-interested and always late for classes, she'd be yapping with the other teachers in the staff room/corridor and would normally (very regularly) arrive 10-20 min late.
Ended up doing ordinary French in the LC because of her. I managed honours Irish and got a respectable grade in that...go figure.
A complete waste of taxpayers money paying her salary.
Mrs O'brian was very un helpful teacher who all of the time favoured girls to boys and seemed to help them more then the boys praised their talents more, and the total opposite to her husband
