C Price felt that classes that went through marked coursework would be useful. MJ Thompson pointed out that the number of 2nd year courses with exercise classes is steadily increasing. There was also a need to have more postdoc students to help in tutorials. RK Tavakol felt that complaints of this type were best settled by students approaching the lecturer directly. Most lecturers do not mind varying their lecturing style but they need to be asked.
