Please take note for your physics tests and exams

For the final answers for all calculations: 

• Do not leave in fractions
• At least 2 significant figures (add a .0 to single-digit number) 
• At most 3 significant figures (round off long numbers to 3 sf) 
• Correct units are always necessary in all final answers

This applies for all physics assessment papers.

Also take note:
You are required to know the SI units and prefixes.
