Nine-hole rounds normally only count toward a player's handicap if they're played consecutively—i.e., two nine-hole rounds played without an intervening 18-hole round. If this is the case, you can record the two nine-hole rounds as a single 18-hole round on the scorecard.

If consecutive nine-hole rounds are played on two different courses, you need to select the "Enter your own course" link during the course selection process. The course rating is the sum of the two nine-hole course ratings (or the average of two 18-hole course ratings); the slope is the average of the slopes for the two courses.

Non-consecutive nine-hole rounds do not count towards your handicap.
