Which missions are on Disc 1 and which are on Disc 2?

If you're playing xbox 360 Mass Effect 3, you might find it infuriating (as I do) that at the beginning of the game is a chop of "INSERT DISC 1" and "INSERT DISC 2" depending on what order you choose missions...

I chose to do grissom academy mission (DISC 2) before going to do the missions regarding Krogan/Salarian. (DISC 1) and I did an N7 mission (DISC 2) before doing another Disc 1 mission..

Does anyone have any idea what disc the missions are all supposed to be on? Surely if you can complete them in any order you shouldnt be switching discs. They got Mass Effect 2 right, anyone know whats up with this one?

It's very similar to the way it worked in Mass Effect 2. Disc 1 contains the first and last missions of the game, while Disc 2 contains the more open middle part. However, as you experienced, some of the early side missions on Disc 2 are accessible while you're still on the Disc 1 part, but this isn't a big deal. Once you get to the Disc 2 part, there is no more disc swapping until you get to the final missions on Disc 1.

Be careful about swapping disks because some missions are time sensitive. If you complete the Krogan / Salarian (DISC 1) missions before moving to DISC 2, you will miss out on the Grissom Academy mission.

That being said, DISC 1 contains at least the start and ending:

Start: Earth, Mars
End: Cerberus, Earth, Citadel

According to Eurogamer, disc 1 contains all the core story mission (Priority:< something >), disc 2 contains the rest (all the N7 missions, etc).
