If you have another chance and you concentrate more on Indo-Pakistan and Islamiat you can certainly get great marks. Here are some suggestions in good faith:

For every day science: Imtiaz Shahid MCQ plus subjective
Islamiat: Again Imtiaz Shahid along with MCQs
Indo-Pakistan Part 1: K. Ali ... From Conquest of Sindh till Aurangzeb Alamgir ( Read every thing and try to remember every thing ). For MCQs Sohail Bhatti will help you in this regard.
Sociology: Hurton and Hurt. This is a great book and read it according to the syllabus. Try to make small notes of what you read and recall it when attempting paper and keep in mind different scenarios in day to day life.

With sligh effort you can improve a lot and score upto 700.
