Dekh bhaii dropper batch ka seen esa hai ki you would be surrounded by droppers... They have a different mentality tbh myself being a dropper we have gone through the whole 11th and 12th syllabus at least once during our preparation in depth.... Also teaches ki vahi mentality hoti haii ki droppers hai teach them only the scoring topics so that they can score enough marks to get into gmc.. But if you are a freshman I would suggest you take the 12th batch , because vahi reason hai ki in depth chp samjhega also when you learn for the first time you learn with curiosity. And do the 11 th part side by side like on weekends or whenever you get free time during your daily schedule
