According to USPA:

Surveys indicate that most people jumping for the first time choose the tandem method. Some drop zones use tandem jumps to introduce students into the solo training programs. Training generally takes less than 30 minutes, and depending on a number of variables, a student may spend only half a day for the training and the jump.

Both the student and the instructor are attached to the same parachute system. They freefall together for around 60 seconds, depending on jump altitude, typically from 13,500 feet. They descend together under a single large parachute with dual controls.

The tandem first-jump training typically costs around $100 less than AFF. Many schools offer video of the freefall and landing.
