Calculus vs. Discrete Math (Course Help!)?

So i'm going into Life Sciences in University this September. I have to choose either one of two math courses: MATH 1A03 CALCULUS FOR SCIENCE I : (For students in science: geared towards applications, with attention to underlying concepts.

MATH 1A03 CALCULUS FOR SCIENCE I : (For students in science: geared towards applications, with attention to underlying concepts. Functions: limits, continuity, derivatives, optimization, curve sketching. Antiderivative, definite integral, techniques of integration.)

OR

MATH 1LS3 MATHEMATICS FOR THE LIFE SCIENCES : (Topics from differential and integral calculus, differential equations, discrete math, chosen for their relevance to the life sciences. )

--> Which course would be easier?
