Your child's birth chart can help determine if they can handle the science stream. Mars, Sun, Saturn, Rahu or Ketu, for the science stream, should influence the fifth house in your child's birth chart. The malefic planets give interest in mechanical studies, while the planets like the Sun, Jupiter, Moon, and Venus are interested in bio, medicine, and creative fields.
