Resource overview
This question paper is listed under Biology in the 2000 examination archive. Its catalogue level is HL. The catalogue session is May.

Subject, year and session labels come from the archive catalogue; the original cover remains the reference if a label differs. A file is not automatically suitable for your current syllabus simply because its subject name matches.
For revision, choose a manageable section and attempt it before consulting the matching markscheme. Keep a short error log separating knowledge gaps, method choices and unclear explanation. Compare the paper number, level and examination zone before pairing files. Older papers can be useful practice, but their topic coverage and format may differ from the course you are taking now.
