When looking at the question of whether to continue in your masters, it is a fallacy to consider the (non-refundable) tuition you've paid. This is a "sunk cost" ( http://en.wikipedia.org/wiki/Sunk_costs ). The question you should ask yourself is simply whether you can pick up the knowledge you want cheaper and better elsewhere. You've not mentioned your other possible options at this point (do you have friends with these skills?), nor the amount of time remaining for the masters degree.
