Biology is freaking difficult

Oh my goodnes...
How am i going to answer biology questions?
I don't seem to able to answer tutorial questions even I have already study.
I can't regurgitate my notes even though I memorized it an hour ago.
Why is it so difficult?
I just do not get it.
Other subjects are fine but not this one??
I understand, but can't write all the points.
And biology is totally about spamming points... this sucks...

I wonder am I able to survive.
