How to Calculate Score From the RPF SI 2018 Answer Key

The RPF SI Answer Key is released on the official website of RPF Constable. The basic method of calculating the score is by subtracting the sum total of the incorrect answers from the correct ones. Here is how one can calculate the RPF SI CBT score:

  • In the answer key, the correct answers are shown in green colour and the candidate’s selection is shown as a blue colour dot. If the answer is correct then the blue dot and the green colour line can be seen on the same option.


  • Count the number of right answers and the number of incorrect ones
  • Multiply the number of right answers by 1 and the incorrect ones by 1/3.
  • Subtract the total sum of the incorrect answers from the correct ones, those are the total number of marks.
  • Formula- (Number of Right answers) x 1 – (Number of incorrect answers) x 1/3. For example, if there 75 questions attempted by a candidate and 57 of them are correct, then (57 x 1)- (18 x 1/3)=  57-6, which is 51. 51 will be the score in this case.
