For question 4a (the one with the modulus graph), for y = 0, I wrote x = 0.5ln(6.25), not noticing that 6.25 can be rooted to 2.5. How many marks was that? Will I get full marks for that one, or do those questions typically require a simplified answer?
Also, how did people find that compared to the June 2015 and June 2013 paper? Those are the ones I didn't do for prep, so I can't judge
