Or video kab aayega sir
Madam this is a good class. But i have a suggestion. In plus 2 level exams, questions come in malayalam. So the mathematical terms will be in malayalam. If you could include the same in your class, like radius = aaram or giving the same question in malayalam it will be more helpful. (
Thank you for your feedback. I will consider your suggestions going forward. I already added few QA lessons for LDC/VEO Exams. Please check and let me know your thoughts.
