You should find a new tutor asap! I know what its like to have that kind of tutor.. My physics tutor only cared about money and whenever I asked questions he would answer them wrongly (hence I would have learnt something incorrect), only to later find out they were wrong. And then he just manipulates answers to fit the given answers etc.
No point spending time with a bad tutor.
Speaking of tutors who don't care about money and are just all around awesome. I had a really good tutor for chem in unit 3, John Wong, absolute beast and we finished the course 2 months before exams.
But straight after we finished the course he informed me that I should probably find another tutor to replace him for unit 4, as he felt like he couldn't teach it to his best ability. Top bloke, didn't waste my time or money, main reason I went from failing Yr11 Chemistry to doing good in unit 3 Chemistry. Unit 4 just isn't the same without him
