Hi there,

First of all in any board you can't increase your mark from revaluation unless it actually have content for an extra mark. If you are confidence about what you wrote in exam and you are sure that you will definitely get more marks when you can consider revaluation. Otherwise your mark will not increase. You can try improvement exam if there is an option. Weather it is 6 or 10 marks you can't increase it if your answer sheet don't deserve that. Similarly, if you had written well and confident about that, you will surely get more marks.

Thank you.
