What TT suggested is a feasible way of getting high marks in English.
Memorising essays as a whole, as many of you pointed out, is not so smart.
However, memorising ideas for arguments pertaining to certain body paragraphs and memorising epic phrases etc is a great idea.
My first SAC for Unit 3 English was an oral so obviously this doesn't apply to that (20/100marks). Second SAC was a Context piece that was written at home, doesn't apply to this either (30/100marks). Third SAC was a text response essay so it DID apply to this. I didn't think of any fresh ideas or points during the SAC. Had 1 hour, regurgitated everything I could that was relevant, finished in about 50 minutes and spent the rest of the time proof-reading etc (30/100marks). Last SAC was language analysis so you can't directly memorise techniques etc but you can memorise different epic generic phrases that you can adapt to any topic (20/100marks).
