# Edexcel C3 Jun 05 - How Did It Go? watch

1. (Original post by ABUSHOMAL///M3)
Is the time in years 13.9
Yes, that's what I put. Many people rounded it up to 14, but I'm not sure why. I remember doing a past paper question as revision about the cost of a computer after t years and that had an answer in years which was a decimal.
2. c3 was kinda strange, consisted of really easy questions and difficult ones, im guessing the grade boundary will be low after hearing that many peeps struggled. I think i lost about 10-15 marks

i think we should write >13.9 , i saw a mark scheme for the specimen C3 paper doing this?
4. or <

I think it would be harsh. I think the question asked for the number of years when there were 1850 orchids? So it's asking for a specific number of years.

*I THINK*
6. i think i put 14, im beginning to think it should be 13 now as it was 13 years + some months.

The question said 'estimate how many years...'
therefore i took 14 as more of an 'estimate' than 13.933...
some of my friends put @ as an angle instead of in radians. If the angle is correct will they still get a mark, as long as you specify it as in degrees?
9. it was very easy although a bit too long
10. true, hope you are right

My teacher said you wouldn't, so they will lose A1 marks. Not sure about M1 marks, imo your friend will get the M1 marks.

I did this last year in my p2 exam, you wont get the accuracy marks but will still get the method marks

They'll probably lose one mark because it specified in the question: 'in radians'

When they said estimate, I think they meant estimate it using the model. Of course, actual results may differ. It might take several years more in real life, but it takes 13.9 years using the model. I think that's what they meant by estimate.
