Hi, I am Rowshan Ara Azad, assistant teacher of DIS,Chandpur. This course is designed for students of STD IX and STD X. Goal of this course is to provide knowledge of Higher Mathematics and resources to the beginners of Higher Mathematics like students of STD IX and also for the students of STDX. I have uploaded contents on set theory, inequality, trigonometry etc. I have put MCQ quizzes with every topic so that the students can evaluate themselves. I hope to enrich the course more in future so that this becomes a valuable resource for the students.
