Can I change the sessions every day?

Yes, If you have registered for the English sessions.

If you want to switch from the morning to the evening batch or vice versa, you can request this when you login to the platform and click on:

Session Schedule & Batch Change
Select the day for which to change the batch
Change the timings and confirm

If you have registered for other languages, if you miss the session, there is no repeat session for your language.
If you want to change to English session, create a support ticket here: https://isha.co/ask-support
