Hello,

It is not clear whether you can make changes in the slot or not as there is no information in which fields you can make correction once the correction window is available. We would suggest you to login with your credentials on July 10, 2020 at 10am and try if you can change it or you can also contact the helpdesk by sending an email to enquiry@aieeseprimary.co.in

They will help you with your query so that you can change you slot on July 10, 2020.
