Guys I had been a part of True north Learning system located in Bandra for 11th & 12th Maths subject. Its a very good coaching class and they have a very unique teaching method.
Tge best part of tgis class is that they gice personalised attention to all students and they conduct tests on weekly basis and make you prepare fir test papers and also check papers regularly and give you individual feedback on tests conducted.
They helped me a lot to improve my maths and they also taught me a lot of simple and useful techniques to solve complicated Integration and differentiation problems. Best class for 11-12 th mathematics subject
