Biology..??

The subject Biology,
Disturb my mentality.
Where lots of practical,
Make me critical.
Living & non-living are the matter,
Notes are difficult to be gathered.
When the Exam is on head,
It’s time to be mad.
As the paper is going,
Thinking; in previous what was I doing.
For the result - I went like a hero,
But in the life I became a zero.
Here is a question,
To the Minister of education.
Biology … Biology …
Why it make me so crazy..??
