Summarizing sources instead of building an argument
In Part B of the EOC and in the IWA, students often walk through each source one by one instead of using sources as evidence for their own claim. Scorers reward a clear, original argument that draws on sources, not a report on what each source says.
Skipping attribution on paraphrased ideas
Attribution is required for direct quotes and paraphrased ideas. Many students attribute quotes but forget to acknowledge paraphrases. Any idea that originated with a source needs to be credited, even when you restate it in your own words.
Treating the oral defense as a formality
The oral defense is scored. Students who cannot explain their own evidence choices or respond to a challenge to their argument lose points they earned in the written piece. Prepare specific answers to likely questions about your claim and sources.
Running out of time on Part B
Ninety minutes sounds like enough time, but students who spend too long reading all four sources before writing often rush the essay. Skim sources for relevant evidence first, draft a claim, then return to sources selectively as you write.
Letting team dynamics hurt the IRR
The IRR is graded individually, but students sometimes write it as a group document or let their argument blur into the team's shared position. Your IRR must present your individual perspective and lens, even though it connects to the team's broader investigation.
