SAT Biology Subject Tests

I’m going to be taking the SAT this upcoming spring and I was wondering if anyone knows what the difference between the two biology subject tests are. (Biology E and Biology M)

The Biology Ecological (Biology-E) test leans more toward biological communities, populations, and energy flow. The Biology Molecular (Biology-M) test is more geared toward biochemistry, cellular structure and processes, such as respiration and photosynthesis.
