Any last minute advice/tips for text response? its the section i'm most worried about.
How did you approach it?
I wrote text response second in the exam.
Conquer language analysis first and approach text response next. My advice would be to glance over at the topics for the text response before you start the language analysis as soon as they begin the exam. You'll have one of two outcomes:
1) You look at the two topics and one topic stands out as the one which works for you really well (ie. you remember quotes for it, its a topic you have planned before, even better its a topic you have written on). If that's the case, quickly take 2-3 minutes sketching a plan for it next to the topic so you won't forget when you come back to do it. This is the preferable option

2) You look at the two topics and you're not sure which one is best for you - you feel as if you could write reasonably well on either but you're not sure which one you can approach best. If that's the case don't worry too much - I'd suggest get back to language analysis and smash it out, and let the topics simmer in your brain - with any luck (and this WILL happen) more information and ideas and quotes and all the good stuff will start to form in your brain as you language analyse to death and when you move on to text response it will be clearer.
When you read the topics please make sure to highlight and/or underline the key words in the topic. It's really easy in the pressure of the exam to miss an important point in the topic and lose marks that way. Don't lose those easy marks. Make sure your essay is really addressing the prompt. Ask yourself WHY and HOW.
Also make sure you ARE addressing the topic all the way through the essay - don't start meandering off into the trails of english analysis (if you're so inclined). A really good thing to do is to have the topic in front of you all the time. I did this by placing my exam next to the paper I was currently writing on and glancing back every now and then to check to make sure I wasn't losing track.
Don't be afraid to take 5 minutes to write an outline/structure for your essay - it helps heaps and ensures that you are logically building your argument. I would advise against writing blind and letting whatever comes out of your head just on to the paper.
Another tiny tip which can add real zing to your conclusion is to save a powerful short quote that sums up your argument for your conclusion and adding it in to tie your whole essay together. I did that with Henry IV and it worked pretty well

Good luck!
