FAQs on BITSAT Past Year Paper- 2016 - BITSAT Mock Tests Series & Past Year Papers 2024 - JEE

1. What is BITSAT and how does it differ from JEE?
Ans. BITSAT stands for Birla Institute of Technology and Science Admission Test, while JEE refers to the Joint Entrance Examination. BITSAT is the entrance exam for admission to the Birla Institute of Technology and Science (BITS) campuses, while JEE is conducted for admission to various engineering colleges in India. The main difference between the two exams is that BITSAT is specific to BITS campuses, whereas JEE is a national-level exam covering multiple colleges.
2. What is the eligibility criteria for appearing in BITSAT 2016?
Ans. To be eligible for BITSAT 2016, candidates must have passed the 12th examination of 10+2 system from a recognized central or state board with Physics, Chemistry, and Mathematics as compulsory subjects. They should have also scored a minimum aggregate of 75% marks in Physics, Chemistry, and Mathematics, with at least 60% marks in each of these subjects.
3. How can I prepare for BITSAT 2016 effectively?
Ans. To prepare for BITSAT 2016 effectively, you can follow these tips: - Understand the exam pattern and syllabus thoroughly. - Practice previous year question papers and sample papers to get familiar with the exam format. - Make a study schedule and allocate specific time for each subject. - Focus on strengthening your concepts in Physics, Chemistry, and Mathematics. - Take regular mock tests to assess your preparation level and improve time management skills. - Seek guidance from experienced teachers or join a coaching institute if needed.
4. Is there any negative marking in BITSAT 2016?
Ans. Yes, there is negative marking in BITSAT 2016. For each incorrect answer, one mark will be deducted from the total score. However, no marks will be deducted for unanswered questions.
5. Can I change my BITSAT 2016 exam center after submitting the application form?
Ans. No, once the application form for BITSAT 2016 is submitted, the exam center cannot be changed. Therefore, it is important to carefully select the preferred exam center at the time of filling the application form.
