Hay Alex!
First of all I'm so happy to hear that you get through the exam! So did I! I told you that we were able to pass it!.
You're so lucky to have parents like that. My mother didn't give me money because she says it's my obligation. I'm always try to do my best but to be honest I don't feel that back me up and that makes me feel quite sad.
Anyway, have you hear about the new mario car games that has just gone on sale? It seems to be really cool and it has a really good review and also it's not expensive at all.

You did a really nice job, but there are a few corrections I would make: ‎Hey Alex!

You're so lucky to have parents like that. My mother didn't give me money because she says it's my responsibility to earn money for myself. I'm always trying to do my best but to be honest I don't feel that back me up ("I don't feel that back me up"? no entiendo... ) and that makes me feel quite sad.
