Hi Christine,

If you mean to ask what the difference is between the two courses, then the normal Biology course is a lot more thorough and extensive, while the High School Biology course is more selective for information that is normally studied at the secondary school level. Further, the High School Biology course requires more prior knowledge, so the normal Biology course would be better if you want to start studying the subject from scratch. 

If your question had a different meaning, or if you have any other questions, please let me know!

Thank you, that's helpful!
