Well. I’m assuming that you have studied well throughout 11–12.
If yes, then YEAH. It is possible. BITSAT is a test designed to test your instincts and quick thinking. If you’re clear with your course, you can manage to clear the test with ease.
But if you are the other side of the party who fooled away in 11–12, then I’m sorry to say that you should drop all your hopes for clearing the exam with a weeks time. People spend years after years trying to clear the exams and questions like these are an insult to them on the face.
But, miracles happen. Luck changes. Fate changes.
