The 0 was the only thing i put on the graph apart from F(N) and t(s) on the axis. And obviously the graph xD :cool:

what shape was the graph meant to be? :confused:

Triangle although you can have curves as in real life the graph would not be a perfect triangle

i think i put in the numbers too but i put the seconds midway(peak of triangle)- ill probably lose the mark won't i?

Just had a quick look at the grade boundary for an A over the past few years:

2010 = 67/90
2011 = 64/90
2012 = 66/90
2013 = 61/90
2014 = 60/90

Considering this year's exam was probably similar in difficulty to the past 2 years, it wouldn't really be unrealistic :smile:

2014 was 63?

It's 60 on the SQA grade boundaries document :s-smilie:

Are you sure?

I sat the old higher paper and I have just realised that for question 21 the projectile question while sitting the exam I did the question however I then realised that I had done it wrong so I did it again and got the right answer but I now have a feeling that I forgot to cross out my original wrong answer. Does anybody have any idea whether or not I will get any marks for this or will I just get nothing? :confused:

(OLD HIGHER) For the capacitor question with the body instead of dividing the voltage by the smallest resistance i divided by the biggest resistance -_-. I wrote the I=V÷R equation though would i get at least 1 mark for that? Also on the FT graph i accidentally thought the force had an extra 0 on the end from the first calculation but my graphs correct otherwise will i only lose 1 mark there?

Also for the question where u had to work out the voltage across the Variable resistor did anyone else take the voltage from the LED away from the Vtpd(which is the emf minus lost volts)???
