Hiii,

B.Sc. Life sciences is a programme course consisting of 3 main disciplines of biology - Botany, Zoology, and Chemistry. It deal with the study of life forms and its interaction.

On the other hand B.Sc. Biological Science is an honours course (interdisciplinary) which also include the mathematical and statistical aproach towards biology. It may include physics and mathematics also.

Hope I solve your query.

All the best!!!!
