Hi Shafi
The ranks of any entrance exams are decided on the basis of the score you get in the entrance exams conducted. Even if the exam is difficult, there nothing to be considered. You'll get a rank according to your score and the number of students who scored more than you. And in cases of 2 students getting same mark, the higher rank will be given to the student who scored in a specific subject, mostly Mathematics, and that differs. There won't be any other consideration for any student as the test is difficult.
Good Luck.
