Hello sir,

.

I haven't Heard about ocarina exams anywhere till now, I'm comfused that have you made any spelling mistake or i don't know about it.

By the way most let me help you in one way.

Most important topics in biology you will get in every exam.

• Macromolecules
• Cells
• Mitocondria
• Evolution
• Botany
• Zoology
• Cell biology
• Eukaryotes
• Ecology

Cover the answers relating to it.Its more enough for examination

If i haven't  your point,ask me for more questions..I will clear your point with pleasure.

Thank you
