Admission to BITS Pilani is based on various factors, including your score in the BITSAT exam, your academic performance, and other factors such as your category (OC in your case) and availability of seats. The cutoff for BITSAT varies each year depending on the difficulty level of the exam and the number of students who appeared for the exam. Generally, a score of around 280-300 out of 450 is considered a good score for admission to BITS Pilani. With a score of 120 in BITSAT it is highly unlikely that you will get admission to BITS Pilani. However, I would advise you to check the official cutoffs for the previous years and also check the admission criteria for other BITS campuses like BITS Goa and BITS Hyderabad. Additionally, keep in mind that BITSAT score is not the only factor considered for admission to BITS. Your academic performance, extracurricular activities, and achievements also play an important role in the admission process.
