Hey guys, not sure who else is deciding on the earth sci/enviro sci concentration but I have some really important information regarding scheduling:
2GI3 is semester 1 and there are a few possible options for lab times, this one is required.
Of the 4 "choices" for the second required course, only 2B03 (soils) fits in semester 1, and 2Q03 (geochemistry; with the recent change in the course schedule) fits in semester 2. 2A03 and 2W03 will have conflicts.
The two above are both good options. However, much (but not all) of the content in 2Q03 will be covered in the biochemistry content in iSci... so Luc has advised that the course is only required if you are planning to take courses in the future in which 2Q03 is a prereq (I believe there are 2 or 3 courses in which this is the case).
For me, I am planning to take 2I03 (earth processes; another course required for many courses as a prereq) this year in semester 2, and will take try to take 2W03 next year... although this does not follow the concentration layout, I have gotten the OK for this, as long as I promise to do one of the 4 on the list next year. I'm sure anyone else will have the similar approval if they choose this path as well.
Hope I was of help, and talk to me if you have any more questions about the Earth Sci concentration. But otherwise, compared to say chem, biochem, or chembio, it seems pretty chill.
