Resource overview
This markscheme is listed under Chemistry in the 2003 examination archive. Its catalogue level is SL. The catalogue session is November. 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.

1. Follow the markscheme provided, do not use decimals or fractions and mark in RED.
2. Where a mark is awarded, a tick ( 9) should be placed in the text at the precise point where it
becomes clear that the candidate deserves the mark.
3. Sometimes, careful consideration is required to decide whether or not to award a mark. In these
cases write a brief annotation in the left hand margin to explain your decision. You are
encouraged to write comments where it helps clarity, especially for moderation and re-marking.
4. Unexplained symbols or personal codes / notations on their own are unacceptable.
5. Record subtotals (where applicable) in the right-hand margin against the part of the answer to which
they refer next to the mark allocation. Do not circle subtotals. Circle the total mark for the
question in the right-hand margin opposite the last line of the answer.
6. Where an answer to a part question is worth no marks, put a zero in the right-hand margin.
7. For each Option: Add the totals for each question in the Option and write it in the Examiner column
on the cover sheet.
Total: Add the marks awarded and enter this in the box marked TOTAL in the Examiner
column on the cover sheet.
8. After entering the marks on the cover sheet, check your addition to ensure that you have not made
an error. Check also that you have transferred the marks correctly to the cover sheet. We have
script checking and a note of all clerical errors may be given in feedback to examiners.
9. Every page and every question must have an indication that you have marked it. Do this by writing
your initials on each page where you have made no other mark.
10. If a candidate has attempted more than the require d number of Options within the paper, mark only
the required number of Options in the order in which they are presented in the paper, unless the
candidate has indicated the Options s/he wants to be marked, on the cover sheet.
11. A candidate can be penalized if s/he clearly contradicts him/herself within an answer. Make a
