As far as I remember, RC part comes after the first 10-12 questions. Once you are through with the 1st 12 questions and if RC appears as the 13th question, just chill. click whatever you want and let it go. The score is decided by the number of correct answers you give in the 1st 12-15 questions and the last 5 ones.if it appears on the 8th or 10th position then be careful with the answers. Again, if your synonyms and understanding of the sentence structure are good enough, these questions should not be a problem. However be careful with the answers you choose. All the answers seem to be right(I did the guess work on this part and scored 410 on an average).
