1. yes me too

2. It is too useful for me. My chemistry teacher Mr. Shyam Sir given me and my classmate this link on our school group and it is too helpful for me and my friends. This is the time of pandemic and in this time it becomes too useful for me and my friends.
Thanks to my Sir and to this website.
