The workload dumped on you by CTC is on a different level to anything you would get in the first year of undergraduate studies nevermind GCSEs. The sheer volume of stuff is like drinking from a fire hose and requires total commitment day in day out to keep on top of it
I have to say I wholeheartedly agree with this sentiment. Being in the process now, it's much more intense than the majority of my undergraduate ever was, let alone GCSEs. In the run up to exams it's safe to say you lose your entire life and I personally stay at CTC until about 11pm each night.
