Mayank kothari or satish jalan - sfm new course

bro i have no idea about satish jalan but I'm taking pen drive classes from mayank Kothari and he is really good. his videos are not like others like 2 or 3 hours in one go rather each concept and each question have separate video and avg duration is 5 to 10 min and you get restriction not in terms of views like 2 or 3 rather you get unlimited views for the period like 6 months or 1 year you bought video for. and he is available for queries on inbuilt doubt solving pan in software as well as on WhatsApp.

Mayank sir
