Hi,i remember you posting about this before. Yes,the intensity of the course is right,and this is how ALL cabin crew courses are carried out,regardless of airline.
If you feel the points system and the way in which it is being used is wrong,then maybe speak to the people who organise the course, i know its a private company, speak to someone in the offices.If the rest of you who feel the same way also do this,maybe they will do something about it?
You are lucky that the pass rate is 70%,most airlines it is 85-90% however you must understand that there is a reason for the pass rate - Your job is about safety, and if on an exam you can only get 50% of the stuff right, how will you cope putting the theory into practice if such a situation was to arise?
Speak to someone at the company running the course and see if they can help you out.
