According to the overall qualification measures for BSc Nursing you want to pass 10+2 with at least half checks and Physics, Chemistry, and Biology as mandatory subjects. At least fundamental information on Maths is expected for Physics, Chemistry, and in some cases Biology (little PnC for Genetics). In any case, top to bottom information isn't by any stretch of the imagination required, so there is no impulse to read up eleventh twelfth maths for BSc nursing.
