I am a first year life sci student... and at this moment....i have a choice between Macro econ ( econ 1BB3) and environmental sci 1A03...which one is easier????

I would say Environmental Science 1A03. I heard a lot of people say it's quite an easy course but again, the definition of "easy" may differ from one person to another. The workload isn't much though I believe. I'm taking it right now and I find it interesting and I like the professor that teaches it.

I agree with nino. I'm also taking it right now and I love the prof who teaches enviro 1a03: he's enthusiastic and very clear on what he says. But I think I heard from somewhere that the course is already full unless some people decideds to drop it (which is highly unlikely). Make sure you check SOLAR before making any timetable plans.
