FBISE SSC cheat sheet

An MCQ has one stem and four or five options; exactly one option is the key, the rest are distractors that must be wrong but plausible.

Eliminate options containing absolutes such as always, never, only, and all unless the stem itself states an absolute condition.

When two options are logical opposites, the key is usually one of them; test both against the stem before choosing.

Numerical MCQs: substitute each option back into the given formula rather than solving forward, which is faster under time pressure.

Unit check rule: an option whose unit differs from the quantity asked in the stem is automatically a distractor.

Negative stems (NOT, EXCEPT, INCORRECT) invert the task; mark the word first, then select the option that does not fit.

In FBISE papers, no marks are deducted for wrong answers, so every item must be answered; leave nothing blank.

Order of operations for calculation items: brackets, indices/powers, division and multiplication left to right, then addition and subtraction.

Marks map to points: a 2-mark question needs two distinct scored statements, a 5-mark question needs about five, each on its own line.

Definition-plus-example is the standard two-part structure for short questions; a definition alone often loses the example mark.

Derivations must show the starting equation, each algebraic step, and the final boxed result with units; skipping steps loses method marks.

Diagrams require a title, labelled parts, and a caption; an unlabelled sketch earns little credit even if correctly drawn.

For 'difference between' items, answer in a two-column table with the comparison basis named in each row.

Numerical answers carry units and significant figures; a correct number with a wrong or missing unit loses a mark.

Long-answer structure: introduction, headed body sections, worked example or diagram, and a one-line conclusion.

If time runs short, write the key formula and outline points for remaining questions; partial credit is awarded for correct method.
