^ I thought text response consumes more time than context?
Anyway, I really like the context so I will write it first, then language analysis and text response
Having said that, depending on the questions as well, I may change my mind
What do you suggest? Which section should we write first?
It entirely depends on what you are comfortable with. If you're more of the "analytical" mind I suggest you should use your reading time effectively and start with LA->Text Response->Context.
Having said that, Context is a nice break in between the other two sections.
Knowing me, I would probably start with Writing BP's of Text response-> Start context-> write BP's of LA-> Finish rest of Text Response-> Finish rest of LA-> Finish context...with style.
I'm a bit all over the place. 
Wow, how can you do that?
Like how can you estimate the space you need to write for conclusion?
Yeah, probably writing LA first is better as we use reading time for it
Btw, what do you think about writing context before the text response? Do we have enough time to finish it?
As a rule of thumb, you should generally have your context idea already determined(flexible), therefore your essay is almost 50% done come exam time. Then again, I'm not entirely a good example, as I write creatively and just get very excited with beautiful "flowery" language...this leads to me finishing my context piece in <30 mins. Obviously this gives me more time to work on the analysis sections.
I don't know. I get bored easily, and the more I concentrate on one essay, the more I stress, the more I stress, the more I can't write/think clearly, and then I just turn into a steaming tomato.

So I just like to change it up. I know that for me, doing the body paragraphs first is very important (as I tend to forget the ideas that I have figured out...or eventually add something that I have not included in my introduction) ...it allows me to explore the meaty-end of the discussion first. Intro's and conclusions aren't that long anyways, I just leave a page for each (and write PTO on the side...).
It works for me.
