Class 12 with biology and maths. How many entrance exams did your child register for?

Daughter is in class 12 with biology and maths both. Registration windows will start soon. She has a list of seven exams written on the whiteboard in her room. Some for medicine, some for pharmacy and biotech, two for BSc programmes. I do not want her preparing for seven different papers in her board year. How many did your child sit for, and which ones did you later feel were not worth it?
