The biological subject is not really hard to learn. there's a lot of thing that i learn in that subject just like
psychology-is a process of life or way of living.
prenology- study of brain structure and mental ability.
psychology-study of human mind and behavior
actually i don't know that there are 4 challenges in psychology but when i already attend that psychology class i learn that the 4 challenges in psychology are the complexity,self awareness,casuality and reactivity
i never know that the psychology have a purpose in our life, i never realize that everything happens for a reason but when i already attending the class i realize that everything is connected to each other and have a purpose.
there's so many thing that i wan't to learn so that i promise to my self that i'm going to study more :)
