My son is studying banking in Polytechnic. He tries hard, but is constantly failing in his studies. He has to repeat a year and the fees are piling up. How do I help him?

Do speak to him and the lecturer (if it is possible) to find out the reason why he is constantly failing in his studies. Could it be banking is not his interest or could it be his part-time job is taking too much time?

I think you should have a talk with him, to find out what may be the problem that he constantly fails.

Is it due to his part-timing causing him lack of stamina on his studies? Like Tat Tian suggested, to take 1 semester break to work and save the money, else to fully concentrate on the studies?

Or could it be he is struggling to complete the course which he doesn't enjoy studying? If so, will it be better to drop the course, though seemingly wasting money but constantly failing and repeating the modules is just as costly? Maybe he can temporary join the work force, save up the money then go for part-time / full time studies after he is clear what he is interested in.
