Bio 1A/1AL over the summer

I’ve heard many bad things about taking Bio1A over the summer. People say that it is harder in the summer because it is condensed in a shorter time. But wouldn’t devoting one’s entire summer to one hard class be better than taking that class concurrently during the semester with other classes such as Chem3a and Physics8a?

I would also want some input about what other classes I should take instead over the summer if Bio1A is really as bad as people say it is. Maybe Chem3 or Physics8?
