from my experience i can say it is really an easy exam ..exams that i had appeared in NUST entrance test , and those of FSC papers of Federal board , then i have appeared in various job tests,including FPSC drilling engineer test ,atomic energy commission tests, all were very difficult .
80% course was of matric and FSC level.
Even English Precis papers was not much difficult ,if we look at FSC level english paper it is also of the same level of difficulty.
Essay is the game of luck ..if it comes from the topic you have practiced you can easily handle it. Rest of all papers were very easy .if some one really work hard ,he can surely do that.
