Resource overview

This markscheme is listed under Biology in the 2000 examination archive. Its catalogue level is HL. The catalogue session is May. The information below helps you identify the document before opening the complete PDF. 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.

Use this markscheme alongside its matching question paper. Attempt the questions first, then compare the required reasoning and the available marks. Record the exact step that lost credit rather than only the final answer. Examiner wording can help you distinguish a calculation error from missing explanation, but an older markscheme may use a previous assessment structure.

The public preview contains file information and, where reliable text extraction is available, a limited opening excerpt. It is not a summary of unseen questions or a replacement for the original document. Create a free email account to read or download the complete file. No payment is required to unlock this archive resource.

This original usage overview is based on the archive metadata. It does not claim to summarise the complete file.

Opening excerpt

Opening text only, limited to at most 20% of pages, two page-equivalents and 2,200 characters. Clearly labelled personal identifiers have been removed. Text extraction may omit equations, tables or figures.
