Biology – Frisco ISD Question Bank

Do one topic per day. Each topic has 10 questions — start with the worked example at the top.
Print the question sheet and work on it by hand (just like on a real exam). Use the lined space provided.
Check your answers using the Answer Key only after you've attempted every question.
Start with Easy questions to build confidence, then move to Medium and Hard.
Keep the Reference Sheet handy while practising — but try to memorise key terms over time.
