Other Bio classes to take besides 1B (for PreMed)

An upperclassman I know at Cal strongly suggests to take a different biology course than Bio1B to fulfill the year of bio for med school reqs. He says though the class material is on the easier side, the class curve is terrible and it’s pretty difficult to get an A in the class. This was a while ago, and I’m wondering if the curve is still just as bad since the grade average for 1B is a B-, which is a bit low considering how easy people say it is.
What other biology courses are there that can replace 1B? I was looking into anatomy and physiology classes (MCB 32, IB 131, IB 132, MCB 136). If what he says is true and it’s better to avoid bio1b for its curve, what other biology course would you recommend?

For reference, I’m not a IB or MCB major so I don’t need Bio1B for any major requirements and I also plan to take Bio1A for the other half of the year of biology req.
