where do i set the mark book parameters.
i need to set the markbook and report book to calculate the students marks in five units and to calculate and give average,
sum up each and every subject, total and give average,
arrange the students from the 1st to the last,
arrange all the subject from the 1st to the last

Hello! As a starting point for this, you may want to enable column weighting. This is a two-step process - first you will need to go to the bottom of System Settings in System Admin and change your default grade scale to Percentage. Then, go to School Admin → Markbook Settings and enable column weighting. This should allow you to calculate average grades within Markbook. Hope this helps!
