Yes, with 68% in Class 12 (PCB) and being in the general category, you are eligible for B.Sc. Nursing through ACPUGMEC in Gujarat. Admission is based on 12th marks, and while top government colleges may have higher cutoffs (usually 75–85%+ for general), you still have a fair chance of getting a government or aided college seat, especially in lower-preference institutes. Final seat allotment depends on the merit list and available seats, so fill a wide range of choices during counselling.
