Some videos are not uploaded or Maybe has been deleted but worry not because notes related to every chapter will be equally helpful to y'all.

all together here there are 30 videos
1 lecture video = Your 4 days to practice
therefore 30 lecture videos = 120 days of your practice.
120 days = 4 months
in between 4 months you'll not only study, there are few occasions, emergencies and vacations as well which sometimes becomes compulsory demanding for you attendance so carry 2 months for these social/psychological stuffs.
now 4 months of practice + 2 months extra = 6 months
start preparing and give 6 months only to your syllabus resonating to your board examination and not to class test, unit test, assessment test, pre board or annual/half yearly exams, don't bother about these tests to disturb your academic flow. if you wanna do good in these examinations/tests then work extra hard seperately for these tests/examinations of school.
