Seating arrangement: place fixed-position clues first (facing centre means left is clockwise), then apply relative clues outward from the fixed point.

Odd-one-out and analogy: identify the shared attribute (category, function, part-whole, or degree) before comparing surface word meanings.

Average = sum of items / number of items; if every item rises by k, the average rises by k.
