For all this Sn1 ans Sn2 business surely the answer for suggest a mechanism was neucleophilic substitution and you wouldn't have to specify Sn1 or Sn2. I make this assumption because we have to bare in mind that this was a paper aimed at year 12's and the Sn1 and Sn2 is a year 13 thing. Which leads me to believe that a fair few of you are in my position which is people who are resitting and are in year 13, hence you mentioning Sn1 and Sn2 which may have been over complicating the question. Also us year 13's dont even know how to decide weather a secondary will undergo Sn1 or Sn2 so I doubt they would expect a year 12 to know. I'm not saying I'm right but that's just my thought on the matter.
Year 12's are expected to know the Sn1 and Sn2 mechanisms, and be able to draw them fully. And the Facer book does tell you which undergo which, and which prefer which. There is a graph with different speeds etc in the book.

I have read the spec and I cant see it that for unit 2 that they are expected to know the Sn1 and Sn2, also the facer book goes into way too much unnecessary detail.

If you find the spec online, page 43, 2.11 section f, "describe the mechanisms of the substitution reactions of halogenoalkanes and those in.."
I interpret that as being, be able to both draw, and write what happens. Also, based on past papers, the question is nothing new, and has been asked in previous papers.
You say it goes into unnecessary detail, but, clearly not, as a question came up that could've been answered if you had looked in the George Facer book.

You MAY be right on your stance about the Sn1/2 buissness, but you are most definitely wrong about George Facer text book. It certainly DOES go into way too much unnecessary detail, but it's still a brilliant book to have

I'm sure the facer book is good however I believe that it is filled with certain information that is way to advance and somewhat unnecessary information for that specific unit.

Well I interpret that as the Nucleophillic substitutions with halogenoalkanes and their mechanisms with other Nucleophiles such as water, Ammonia which are all in the spec along with a hydroxide. And it has only appeared once in regards to drawing the transition states as far as I can remember

Yes, so like I said, this is in the spec. And in past papers.

I didn't say it was all needed, I myself skip certain bits, but, this bit is obviously needed, as a question came up on it.
(I stack all my books on my desk and work through each section from each book, that way you learn what is on the spec / is really important, as it appears in all the books)

Well the Sn stands for Nuecleophilic substitution so we are both right haha and as it is a secondary it can under go 1 or 2
