Indeed, you can. You simply need to request that your school permit you to return for class 11. To change school then, at that point, take a school-leaving declaration from your school and take admission in class 11 of some other school.

To rehash class 11 taking trade you can make it happen.

However, again on other hand, you will lose two years in finishing eleventh and twelfth rather than simply losing a year in re-showing up for class twelfth.
