Don't worry Its not a big deal.
What you need to do is to Close your eyes and relax.Say yourself that you can do it because believing in yourself is the first step to sucess.
Now coming to the practical steps; there are repeated questions of IndoPak History given by our respected Last Island sisy;give one or two readings to these question to make yourself familiar..now divide these questions into lets say seven or eight parts and start working daily on each part one by one ..In this way you can easily cover each paper in seven eight days..maximum 20 days mein ap k dono paper cover ho jain gy..no need to be worried or to go into depth and making yourself tense..you'll improve gradually..then revision mein bht kuch cover ho jata hy..
I hope it'll work for you.
All the best
