Rating concern influence future studies

This is not a review, nor a rating, hence average is selected. I would like to enter my son at Intec College for a computer course, but looking at all the existing ratings, I am not sure if this is the right thing to do. I do understand that all ratings are of a subjective nature, but I need to be confident that I make the right decision. Is there any person that actually gave a good rating to Intec ? Thank you L Pretorius
