Last year an aptitude test was conducted for the streams you want to opt for. I luckily passed and stream of my choice(science) was provided to me.But under certain circumstances I did not manage to pass the finals.And I failed and the school tells me to repeat class XI in humanities.And i do not want to repeat class XI with any other stream,I want to repeat in science stream.So the question is Shouldn't the school be allowing me to repeat in Science stream? Can I change the school and repeat in science stream?Should change my stream option and opt for any stream that the school provides?And what if I take up Science stream and can i change my stream in half yearly if I don't perform well?
