Im 30 years old can i study bsc nursig?

To study B.Sc. Nursing at St. Xavier's Catholic College of Nursing, you need to meet certain eligibility criteria. Generally, for B.Sc. Nursing, candidates must have completed 17 years of age and there is often an upper age limit, which varies. For example, in Tamil Nadu, the maximum age for B.Sc. Nursing was previously set at 30 years for general candidates and 35 years for SC/ST candidates as of 2017. 

Given that you are 30 years old, you may still be eligible if the current upper age limit is 35 years or if there are no specific age restrictions for general candidates at St. Xavier's Catholic College of Nursing. You should contact the college directly for the most accurate and up-to-date information regarding their age eligibility criteria.
