(16.01 + 16.02) + (16.03 + 16.04), the classes collectively known as unified, consist of 5 subsections, (Fluids, Thermodynamics, Materials and Structures, Signals and Systems, Computers and Programming) linked together by a common teaching staff and (somewhat) coordinated lectures.
It is the general belief of most students at the institvte that Unified is one of the most hard-core classes at MIT. Known to unified students alone, apparently, is the fact that it's really very easy, if you just approach it as 2 classes instead of one.
THe topics in unified tend to be glossed over, so that despite covering just about all subjects related to aerospace design, you dont go into enough depth to feel like you actually know anything.
The major advantage to taking unified as opposed to (2.001 + 2.005 + 6.001 + 16.05 + 6.003) is that the tests are on different days, and there is a small group of people who you can work with to do just about everything. You get out of unified what you put into it, and you can choose to either just get the grade, or really dive into things that interest you, and use it as a springboard for your exploration of that subject.
Attempts to screw over students
Unified is technically listed as two subjects, which means that technically, one of those subjects can have a problem set the week before finals, and the other one can have an exam.
Also, as the class covers multiple discliplines, the "final exam" is really 2 independant exams, covering different material, in the same time slot. This can (and does) lead to the unfortunate possibility of having 5 different exams in two consecutive days. whoopee.
