i didnt fill up form of bitsat bt now i want to give exam then what will i have to do??
You can do nothing about it now.You will have to wait till next year.BITSAT application form was available for a very long time due to Covid-19 pandemic and i think there is no way the application window will be opened again.So, i would suggest you wait for next year.
I hope this helps.
If you haven't filled the form of BITSAT at the time when form was available then there is no option now to fill the form and give exam.
Now, you can apply for the same in next year. Also, you can apply for the colleges through management quota.
Hope this information helps you with your query.
