I put up a lot of efforts in making courses .. i complete the whole syllabus asper jee main and jee advanced syllabus... No ques has ever come out of wht i teach.. but instead of appreciating the efforts i have put in making free courses. So u rated my course as 2 stars ... Its really disheartening to see that. ..the topics mentioned in specific are to sell the books ... U may cover those if you like ..but i dont want to burden other students with unnecessary topics..Hope you will understand :)
