Arre, beta, they are those unit operations in Chemical Engineering that separate mixtures—distillation columns use boiling points, McCabe-Thiele is a graphical method to design them, absorption is for gases, and extraction uses solvents. But my real revision is happening over last night's cold roti, because Dada's pension and my stitching income mean I cannot afford those fancy coaching notes everyone else has. So for me, these are just diagrams to be memorized, not processes I'll ever see in a plant, achha? Allah bless, just let me pass so I can focus on my actual business of stitching blouses without this double tension.
