ANSWER

Hey please listen to my problem and then suggest what should I do..... Actually I was going good in maths till 10 ..but suddenly when I came to 11 everything changed!!!.... I have never taken any tuitions till 10 for any tuitions but did good... But even after taking tuitions I became very bad in maths..... Also when I ask doubts to my teacher they never get it clear to me.... So because of that I also lost interest in maths and now I'm hating it because I don't know how to study... There is no one to help me... And I m very worried for it..... I don't know why this happening to me.... And now in 12 also..... I want to become brilliant in maths but how.... I've lost interest... I really feel not to study maths...... What do I do... Should I change tuition or whhich way is good to study maths...... I also think my way of studying maths is not right.... ??

See first calm down friend.if ur teachers are not able to understand u pls change. See videos how to solve sums. Practice is must spend 2 hrs on maths... solve ncert get ur doubts to ur teachers,google,apps.... then do rd sharma,mtg. U just need concepts clearing. Dont feel frustruated when u couldnt do 1 or 2 sums. Be confident. Each and every person is weak in one or other subjects. Take ur time to understand the concepts and method
