Tricks of the Trade

Okay so tomorrow's exam is bound to be full of little tricks. What should everyone be looking out for?

Some of mine:
- negative values for r. After you square root the r^2 people just put positive. Watch out.
- picking which year, which day, which week or after how many years,days and weeks. Usually borderline stuff.
- When writing difference equations. Make sure your initial makes sense. It can be S1 or S0.

-units of measurement. Sometimes they put side lengths and stuff in 'cm' and then ask for you to 'write your answer in metres' so don't forget to convert.

Don't worry about rounding up your answer. For example, how many people catch the train every day and if the answer comes to 875.67. Don't think you cant have 0.67 of a person so the answer is 875. The answer is 876.
