I feel in integration, Differentiation and Trigonometry the sums should be categorized according to the steps involved and we assume certain things and formulas to get answers.
Tan sums Sin sums Division and theta sums.
Like degree of Polynomial expression and different rolls , LaGrange theorems.
Students wont waste time, more can score above 80 percent and can be more enlighten.
