Hi, I have a couple of questions:
1. If the question doesn't specify do we leave answer in exact form or decimal and would we get marked down for either?
2. If we answer a question and you could take out a common factor - should you do that or not - some past paper answers do it and some don't and would we get marked down either way?
3. What are acceptable abbreviations for proving geometrical questions?
4. do we leave our answer in improper fraction or mixed numeral - if not specified in question?
5. If not specified in question how many decimals should you round to?
Thank You!
1. If it doesn't specify and you have the capability, exact form.
2. Factorising your final answer is something you can do, but it is unnecessary; you won't get marked down as long as you
factorise don't divide3. \(\Delta\) for a triangle, \\ for parallel lines, and the congruency and similarity symbols to name a few. Try not to abbreviate words like "isosceles" unless you are short on time (you will probably be fine even if you do)
4. Improper Fraction is nicer imo, but BOSTES does use mixed numeral at times. Either or
5. If not specified, pick a sensible number. General rule is the most amount of decimal places used in the question (but then I usually just add one to that just to be safe)
