A satchel is a bag that is carried over the shoulder with a shoulder strap and that has handles. This style of bag originates from the messenger bag English students would use for school, hence the traditional Oxford and Cambridge satchel bags. Today, they are incorporated into everyday outfits, and are worn for numerous occasions.
A tote bag is a large bag that is used to carry a large number of items. They started as reusable fabric bags for running errands and purchasing groceries, but have evolved into their own fashion trend. For school, I actually use a tote bag instead of a backpack; it is much more fashionable and convenient and I still have enough room for my MacBook and other school supplies.
