Tutoring can either be agony or bliss, depending on the level of the student.
On sats/suns I do 3 hours extra tutoring, with two different students. Both korean, 1 hr 30 mins each. The first always seems like an eon. He has a textbook that I review with him. He can read from the book, he can answer the questions in the book, his level is quite good. But as soon as I try to take it into his own life and use it about himself, he goes blank, gives me one word answers at best. It is a nightmare. I really need to figure out a way to get him talking.
The second student, whose house I go to immediately after (They are both a few minutes walk from my house) is the complete opposite. His vocabulary isn't perfect, but I don't know what his parents have been spiking his cornflakes (or whatever it is Koreans eat for breakfast) with as he just talks and talks and talks. It's so easy to teach him.
Generally I find tutoring classes go by quicker than normal classes, personally.
