I personnaly am a big fan of the integrated curriculum and it actually helps me when muscle phys is overlapping micro anatomy. It makes for a better understanding of the material.
As for the block schedule, it is great if you are ready, but can be a lot to handle if you are not.
The plusses are that you get to take all you tests in one week, everyone is taking tests, no partying, etc. You have no other classes/lectures, and for a week all you have to do is study for tests.
The minuses are that if you are not ready it will kick your a**. You don't have time to cram.
The one thing that I will note is that you don't take all tests every time. This week we are doing Monday-Micro Anatomy, Tuesday-Physiology, Wednesday-Gross Anatomy, thur off, Friday-Biochemistry. But the following test blocks only have some of them on certain weeks.
The first block is the worst, but I love having the block schedule.
