767,
You can not write the exams in a week..its a full time class from 8.30am to 5-6 pm every day for 6 months..
At the end of the first 4 months you will sit 8 exams(3 days exam),one month off to avoid students turning completely insane.
Then after you complete the second stage ground school (3 months) you will sit another 6 exams.
If you fail 3 times the same subject you will have to sit all exams again...from the first exam sitting you have one year(if you go long distance course) to finish and pass them all otherwise back to square 0!
You are young..if you really want to try it come over..and im sure youll make it..but its not easy and requires you put 7 months of your life towards this study...its not like most unis where you go out wednesday,thursday friday and saturday to go drinking...
Whatever you decide ..good luck!
