wow that is really a predicament, but the cons of Parkville seem much more personal and degrading over the long run, also 3 hrs of travel might seem like a lot but on the train you can always do work whilst on it, and this is no less tiring than doing study at home if you know what i mean, so reckon you should stay where you currently are because these are all risks that you should be willing to take for the betterment of your future, and taking pt everyday is a great life skill for future work as well
