Can I get correction again?

All the students are required to submit exam form for November, 2020 exam , whether he was registered for May, 2020 exam or not.

but students who already registered for May, 2020 exam, set off of exam fee (already paid in May, 2020) is given against in November, 2020 form.

So, you are required to apply for November, 2020 exam afresh. you can choose any center, any group as it's all new form. Fee paid earlier will be adjusted against new form.
