looks like youre ready for an A*
good luck...
you know when i personally used to sit my exams and whenever i thought the exam was easy i did bad... believe me i did, once i thought in physics i will get an A at least, and ended up getting a D...
so seriously i hope you the best, your marks will decide your future, as in what you parents will buy you for summer (
my mum did) and what you will do in the future as a job.
tell us your grades later, not forcing you, only curiosity!
