BITSAT is a little different form other traditional engineering entrance exams as it has the aura and mystery of the EXTRA 12 QUESTIONS surrounding it!
Every student writing BITSAT will be in a dilemma whether to go for the extra 12 questions or should he just leave them and stay away from risk. Different people who have given a shot at BITSAT for the past 4-5 years have given different theories about these extra 12 questions. Some say it is the easiest part of the part while some say they took an unnecessary risk and stuck up with a lower BITSAT score.
According to the brochure:
If a candidate answers all the 150 questions (without skipping any question), the candidate will have an option of attempting 12 (twelve) extra questions, if there is still time left. These extra questions will be from Physics, Chemistry, Mathematics only; four questions from each part. Further, once the candidate has opted for extra questions, he cannot go back for correction of any of the earlier answered 150 questions."
So the important points to be noted here are:
- You need to attempt all 150 questions. You cannot leave any question blank
- You will not be given any extra time to solve these 12 questions
- You cannot go back to change any of the answers
When to attempt these extra 12 questions:
- You have atleast 20-25 minutes left
- You are confident and sure about atleast 135 questions out of the 150 you have attempted
- You have made educated guesses and you trust your gut (for the 15 questions you need to attempt to get to 150)
- If you have any memory based questions left, and you trust your guessing skills, then attempt them and have a shot at the extra 12!
- If you have any lengthy or a method based problem left, then we would suggest you utilize your time in solving it first, rather than guessing it and only then move on to the extra 12 if you have enough time left.
According to BITS the extra 12 questions are more difficult than the rest of the questions. But for the last 4-5 years, almost every BITSian who has got a score of 350+ (sufficient for getting into CSE or EE) claims to have attempted the extra 12. Infact they also claim that the extra 12 are actually easier than the rest of the questions!
So in a nutshell, its all about taking a calculated risk. Afterall, the policy of being too cautious is the greatest risk of all.
