I've been a full-time tutor for 18 years and that's a very very long time. I think if I have a kid early, some of my youngest students can be my children already. Over the course of 18 yrs, I've progressed from a newbie tutor to a more experienced one. I've probably seen the same question in exams over and over again for decades. Therein lies the problem. I find that I'm more impatient over the years, and less willing to try new methods because of past success. I mean, why fix something that works? It's the problem of the transition from a newbie to an expert. Being an expert makes doing things a lot easier and faster. After all, an expert has done the same things so many times and had seen so many permutations of the same problem to be able to solve it at an instinctual level....
