Difficulty of Biology Majors at UCSD

Just as a survey/interest type of thing, what do you think is the ranking of hardest to easiest biology majors

Biochemistry and Cell Biology
Bioinformatics
Ecology, Behavior and Evolution
General Biology
Human Biology
Microbiology
Molecular Biology
Physiology and Neuroscience

Well by nature, this is a subjective thing because the hardest to easiest would depend on the person.

In my opinion hardest to easiest…

Physiology and Neuroscience
Microbiology / Molecular Biology
Bioinformatics
Biochemistry and Cell Biology / Human Biology
General Biology
Ecology, Behavior and Evolution

However these are my rankings, and someone may find Physiology and Neuroscience easy.
In a manner, I find ecology frustrating, so in my perspective its kind of hard.
