What are some bitter truths about Great Lakes, Chennai, PGDM?

Great Lakes Chennai is a dream college of many MBA aspirants but the truth is it is kind of overestimated. One of my friends who is a recent pass-out, unveiled some dark truths about the institute

• The admission process at Great Lakes is highly biased and untransparent. The majority of seats are filled by Management quota thus affecting those who had high percentile and performed excellently in the interview. 
• My friend also told me how Great Lakes charged registration fees for the WAT/PI round and filled those seats with Management quota.
• The rankings of the institute are forged and paid. Don't let these rankings make you believe that it is at par with top B Schools. 

These were some harsh realities about the Great Lakes that I felt anyone planning to join it should be aware of.
