No, unfortunately these classes are not given over paltalk, nor are they given on the masjid's speakers. This class is only available for the brothers at the moment. Inshallah in the future we will have classes available for the women.
Akhi we are still in the beginning chapters of the sarf book, and we just started the third chapter of the conversational book, with a little bit of effert you will be able to catch up inshaa' Allaah. Just come by this Saturday for Isha so we can talk before the class inshaa' Allaah.
Yes akhi inshaa' Allaah and likewise any brother who studied some sarf before and wants to review or feels he can join and catch up, even if he did not study sarf before is welcome to try and catch up. Also we do the conversation book, so whoever can not keep up with the sarf can join that class. It is not a must to sit in both of them. Zaadak Allaahu 'ilma
