Computer graphics exams at this level usually give you a menu rather than a fixed list. A common shape is five or six questions, answer any four in 2½–3 hours; some schools instead make one question compulsory and let you pick two or three more. The total is often 60 or 70 marks, so each question is worth roughly 15–20 marks, usually split into two or three parts of 6–10 marks each. With four questions in three hours you have about 40 minutes per question, which leaves time to check your arithmetic.

The questions come in two flavours. "Discuss/explain" questions ask how a CRT works, why raster scan suits a particular display, how LCD, LED, plasma and OLED differ, what digital images and colour models are, how translation, scaling and rotation work, and sometimes what common MATLAB image commands do, or how animation works and where graphics is heading. "Calculate" questions ask for the adjoint or inverse of a 3 × 3 matrix, the dot product and angle between two vectors, matrix addition, subtraction and multiplication, a transformed point or composite matrix, or the memory a frame buffer needs. The calculation parts are often the safest marks in the paper: the answer is either right or wrong, and if you show every step you collect method marks even when one number slips.

A calm strategy: read the whole paper first, then start with the one or two most computational questions you are sure of (matrices, vectors, transformations), and follow with theory questions you can write fully, with a labelled diagram wherever one fits (CRT, raster scan, colour models, before-and-after shapes). Examiners reward clear work, so lay out each calculation line by line, underline final answers, and use a heading for each sub-part. Leave the last ten minutes to re-check signs in your matrix work; that is where most marks quietly leak away.
