often, you will regret the things you did not do, more than the things you did.

BRING A CALCULATOR TO EVERY EXAM!!!
i spent 5 precious minutes trying to calculate how long i should take for each question, because the prof jumbled up the marks for this exam as compared to the past year papers!! arghhh...
Then i rushed straight in, because time was really a HUGE factor. I wish i could have transferred my spare time from astro paper to this one.
Rushed into some stupid question and ten minutes in, I realized I had no clue as to what I was writing. Damn, I looked at the other question and realized I could do that question better! but it was ten minutes left to write, and there goes 20marks.

NOTE TO SELF, PLEASE READ THROUGH AND PLAN, AND BRING A CALCULATOR SO YOU HAVE MORE TIME TO PLAN QUESTION RATHER THAN CALCULATE HOW MUCH TIME TO TAKE FOR EACH QUESTION!
