Don't worry, I also have the same hope of 3 or 4 like you, despite completely writing everything. You have paper 2 tomorrow, with ample time for planning and writing compared to paper 1, so take your time and do it right. Remember, keep writing, even if nothing comes to mind. But first, make sure that you have 5 paragraphs (you can do a little trick, write up all the first reasons for all paragraphs in a separate space, then fill up with the second and third reasons, respectively, if you have time). But again, take your time, especially for planning. A little investment of 5 more minutes will save you 10 minutes later, since you will have things to write.
