Is the C3/4 June 2016 IAL before the C3 and C4 June 2016 regular paper?
If so, I'm looking forward to doing the IAL as a prep day before. -

I think it's on the same day as C3. If Arsey posts solutions to the paper, you should thus be able to use the C4 questions as extra questions.(Original post by XxKingSniprxX)

How many marks do you usually lose for a careless slip?
Like I integrate something and find to be, let's say 1/2(g(x)) but I be stupid and write 1/4(g(x)) on the next line (assuming I don't go over and check) -

Slightly dumb question but if I wanted to integrate tan x, is this the right way to type it on your calculator? Or should I use the rearranged formula (which I think is -ln cos x)?

I'll disagree with the above. I did precisely this in my C4 exam and lost 2 A1 marks for miscopying it (when I was turning the page).
sqrt(4-4sin^2x)=2cosx in some integration.

depends on what stage you make the mistake. Most of the time the answer marks are correct answer only (written as a1 in mark scheme, if it's a1 ft that means that you can get the answer mark for following through with your working from earlier on in the question) and you'll normally lose maybe another 1 or 2 working marks depending on the specific question, how much it is out of, how the marks are divided etc etc. If you do a method not on the mark scheme and get it wrong you may well get 0 even if you could have got to the solution if you hadn't made a slip up (did this in mechanics last year lol)(Original post by physicsmaths)
It really does depend on the question but I think if the function is correct they give -A1 for form of af(x) then they give the A1 for the correct answer.
