Be aware when reading these samples that they are certainly not PERFECT in respect to all aspects of the assessment criteria.
Some are from the IB samples & some are from past UWC-CSC students.
There may be examples of good writing which include abstracts (which are no longer needed) or very poor citation style (which you need to check conforms to our school requirements - MLA 8)
Be aware that these samples contain ABSTRACTS which are NO LONGER REQUIRED by the IB
