Mam..iam working in engg college..ur way of teaching is very excellent mam..ur teaching is step by step method...i have not seen any video so far..awesome..
I commend the syllabus of JE exam. U post maximum JE syllabus but I need balance topic video please post that balance topics mam because am not have time ..and please explain previous RRC/JE EXAM paper
