Yeah I had it as that, not too sure whether it's correct. Also had an outlier that I didn't include. Sent from my iPhone using Tapatalk

Mine was whatever gives 2.5 Sent from my iPhone using Tapatalk

Well I got 2.5 but not sure if it's right. Sent from my iPhone using Tapatalk

I felt like it was pretty easy except for 1 or 2 questions but I made a lot of stupid errors I think because I just found that it look really long so I didn't have time to check. Sent from my iPhone using Tapatalk

It's correct, gradient is sx/ux which gives time, then you can sub it into sy = 1/2at^2 Sent from my iPhone using Tapatalk

How does the velocity increase? I thought induced current by Lenz's law would 'repel' the cart until it passed underneath at which point it would be attracted back? I had decrease the whole time, beginning to level out at D. Sent from my iPhone using Tapatalk

I fucked up the orbital velocity question, the single easiest question in the paper. Sent from my iPhone using Tapatalk

80 I think Sent from my iPhone using Tapatalk

They were both worth 1 mark each, part iii which specified 'give reasons' was worth 2 Sent from my iPhone using Tapatalk

For the circle geometry, part i and ii, since they ask 'What is the size of the angle...?', were reasons needed? If so, another 2 marks lost. Especially because I didn't read that we needed to copy the diagram.

Damn, probably won't get it then. Don't know why I always skim read the questions -.- Looking at 69/70 now unless I made silly mistakes.

In the question with v^2 = n^2(a^2 - (x-c)^2) I think I left both a and n as +- even though I got the right values. Will I lose the mark for this?

I found part a) ii difficult for relating the composition of glycogen and cellulose to the structure because I never studied that in depth, I found the testing for protein in egg white difficult because I never learnt a method. The DNA stuff was easy, but I think I would have only gotten about...

Changed my mind, this year was even easier than last year so probably 83 or 84 will align to 90.

No

I highly doubt this would be the case in our exam but I guess it's not beyond the Board.

Exactly, a dimer, which is not a polymer. A polymer has many units.

Anyone do Forensics besides me? What are your thoughts? I actually found it more difficult than previous years. Sent from my iPhone using Tapatalk

I think it was on par or a little harder than last year so I can see 80-82 cut off

Yeah I can see C being correct now also.
