Direction Sense
Direction questions track a person walking and turning, then ask the final direction or the straight-line distance from the start. Always draw the path on a North-up grid: North is up, East is right. Mark each leg with its length, apply left/right turns relative to the current facing, and the diagram answers everything. For distance between start and end, the legs usually form a right triangle — use Pythagoras.

⚡ SSC shortcuts & speed methods
The fastest ways to crack this chapter under time pressure — the techniques that separate a 95+ percentiler from the rest.
- Always draw on a North-up grid (N up, E right).
- Right turn = clockwise (N→E→S→W); left = anticlockwise.
- Net distance = √(net EW² + net NS²); opposite legs cancel.
- Shadow is opposite the sun: morning → West, evening → East.
- Coded directions just rotate the compass — substitute everywhere.
⚠️ Common mistakes & traps
SSC is designed so that careless errors here cost you marks. Internalise each trap before the exam.
- Turning the wrong way (mixing clockwise/anticlockwise).
- Adding all leg lengths instead of netting opposite directions.
- Getting shadow direction backwards (it is opposite the sun).
- Applying a direction code to only part of the problem.
