Revision Strategy
Straight Line LAQ: prepare concurrent lines, rhombus/square/rectangle identification, perpendicular from external point to line.
Pair of Lines LAQ: focus on factorising second degree equation to find individual lines, and computing angle between them.
Applications LAQ alternates: Rolle's/LMVT one year, maxima-minima word problem the next. Prepare both.
Differentiation LAQ is often on implicit or parametric — practice both types thoroughly.
Limits SAQs are predictable: standard limit forms or continuity with piecewise functions.
3D Geometry SAQs are relatively short: section formula, distance, direction cosines — score them reliably.
