I have a problem recently I got a maths tutor and each Saturday I go to her house to have a 2 hour session. But the fact is she scares me, the first time I went to her I felt like crying we sat down and she suddenly started testing me on times table and prime number square number etc ,by the way she’s tutoring me for GCSE, I no I'm not thick but was tired and under pressure and when I got something wrong she looked at me like "your a thick idiot". The second week I did actually cried. My dad is the one taking me and we had agreed it would be easier for us if it was on a weekday and earlier as at the moment its 6-8pm . So I asked her and she goes fully booked so I thought fine and since Christmas is coming I want a couple of weeks break to see family etc but I said that to her and she looked at me as if she was disgusted I 'd even ask. So we left it and got on with work she'd had looked and said it too me so blunt, mean and the work was hard and if I didn't get it she frowned at me.
