Hello Safina,

Meanwhile, till the correction window is open, if your certificate is ready then you can upload it and make the necessary changes.  But, if your certificate is not ready, then you have to apply for general category as you have selected earlier. During counselling, you will be put in general category for the further process.

If you upload your EWS certificate during correction window period, then you do not have to appear as a general category. You need to carry your EWS certificate during counselling.

Good luck and stay safe!
