Develop a shorthand, it will help you immensely.
Never write full sentences on a plan; it's not marked, in fact your assessors won't even look at it. Your plan only has to make sense to you.
The example I've used before is: rather than writing 'Shakespeare uses the character of Falstaff as a contrast to Prince Hal, which reinforces the idea of multiple forms of honour. This can be seen in Act 2 Scene 4 when they pretend to be one another in a key turning point for the play.' I'd just write 'S: Falst.=/=Hal --> diff. hon. (2.4)=T.P!'
Also, for certain sections you shouldn't need to plan at all (at least, not by the end of the year.) Language Analysis, for example, can be quite formulaic. Once you know what you're going to cover (context, contention, audience, tone or something similar) then you don't really need to write anything down to remind you.
That said, provided you can write quickly, there's nothing wrong with planning. Friends of mine would plan extensively for 15 minutes and then churn out an essay in 35-40 minutes. So long as you're planning
effectively an amanaging your time, you should be alright
