No they shoot tier 3/4 students on site. The government would rather have homeless bums living and breathing than tier 4 students. Honestly, get first hand knowledge from people at a tier 3/4 you are considering going to. People talk out of their ass on the internet and have no idea what they are talking about most of the time. I have loved my first year at my tier 4 personally and I can say that GGU has worked for me and a number of people that I have met. However, I can't say anything about any other school other than the one I personally attend and even then I can only speak on my own experience. Education in any form is really what YOU make of it.
