It is first of all extremely expensive, for the price you pay you expect to get assistance where needed

It is first of all extremely expensive, for the price you pay you expect to get assistance where needed. I have failed so many times. I have requested guidelines as to what I am not doing right so I can improve. After all, it is an open book exam. I've been heating a brick wall. I requested to apply for a rewrite with revision. I was told it's not going to help me. I enquired what will then help me, anothe brick wall.
