Just sat my chemistry 2.7 Internal. Did anybody else think this was really hard?

I've gotten straight E's in chemistry all year up until I did this today. I am 99% sure I got not achieved! We hadn't done any practice for the ions used in the first question (Nickel and Sulfonium) and they weren't even on the states / appearance resource sheet. I didn't even know where to start writing..
P.S. everyone else in my class was saying it was really easy. Did I do something wrong? I spent 3 months studying for this one internal and none of it payed off.
