If you have an active course in your dashboard, you can raise doubts using our Ask an expert section where all your questions related to the subject/topic selected will be answered within a few hours by our expert faculty. You can raise the doubts using the floating arrow icon on the bottom right corner of your dashboard as shown in the picture below.
Note:Ask an expert option is not available for the Windows application and is only available in Android and iOS devices. We're working on integrating the same to our Windows applications.
