All 32 terms we publish for Synthesis & Argument, with definitions. Reading them through is the fastest way to find the ones you cannot define — then drill those in cram mode until you can produce them without the prompt.

What the synthesis question is testing
Whether you can use sources to build your own argument, not whether you can summarize six of them. The argument must be yours and the sources must serve it.
Minimum source requirement
The synthesis essay requires at least three of the provided sources. Using fewer caps the score regardless of the quality of the writing.
Sources as support, not structure
Organize by your claims and bring sources to them. Organizing by source produces six summaries with a thesis attached.
Using a source against itself
Citing a source that opposes your position and showing what it concedes. One of the strongest moves available and it demonstrates genuine reading.
Handling the visual source
The chart or cartoon counts as a source and is frequently ignored. Using it well is a cheap way to stand out.
Attribution conventions on the exam
Cite by source letter or by author — "(Source C)" or "Chen argues" — and be consistent. Full bibliographic citation is not expected.
Reading period allocation
Fifteen minutes for three prompts. Spend most of it on synthesis, since it is the only one requiring you to process material you have never seen.
Choosing a defensible position quickly
Pick the side with the better evidence in the packet, not the one you believe. You are scored on the argument, not the belief.
The argument essay has no sources
Evidence comes from your own knowledge — history, literature, current events, personal observation. Prepare three or four flexible examples in advance.
Personal experience as evidence
Legitimate and can be powerful, but it supports a claim about experience rather than a claim about the world. Pair it with something broader.
Qualifying rather than picking a side
Many prompts invite a nuanced position. "Yes, under these conditions; no, under those" is defensible if the conditions are specified.
Avoiding the strawman on the exam
Represent the opposing view as its holders would. Readers notice a caricature and it costs the sophistication point.
Rhetorical analysis: the actual task
Explain the choices a writer made and what those choices accomplish for that audience and purpose. Identifying devices without that connection cannot reach the upper rows.
Choosing what to analyze
Two or three choices analyzed deeply beat eight named. Select the choices that carry the most argumentative weight.
Row-by-row scoring, briefly
One point for a defensible thesis, four for evidence and commentary, one for sophistication. Commentary is where the largest single block of points sits.
Sophistication in practice
A sustained nuanced argument, a broader significance, tension held rather than resolved, or a genuinely vivid style. It is awarded for the whole response, not a sentence.
What loses the sophistication point
Sweeping generalization, an unearned universal claim, and ornament in place of precision. Attempting sophistication badly is worse than writing cleanly without it.
Time per essay
Forty minutes each, and all three carry equal weight. Finishing three adequate essays beats two polished ones and an abandoned third.
Writing legibly and completing
An unfinished essay is scored as written. If time is short, write the conclusion sentence rather than a fourth body paragraph.
Reading the prompt's verb
Analyze, evaluate, argue and explain call for different work. Misreading the verb produces a competent essay answering a question nobody asked.
Synthesis essay
Uses at least three provided sources to support an argument of your own. The sources serve your position, not the reverse.
Common synthesis error
Summarizing each source in turn. That produces a report; the essay needs one argument with sources woven in as evidence.
Citing sources on the exam
Reference sources by letter or author, and integrate quotations into your own sentences rather than dropping them in whole.
Rhetorical analysis essay
Explains how a writer builds an argument for a purpose and audience — not what the passage says, and not whether you agree with it.
Argument essay
Takes a defensible position on a prompt and supports it with evidence from your own knowledge, reading and experience.
AP Lang essay rubric
Six points: thesis (1), evidence and commentary (4), sophistication (1). Almost all separation between essays happens in the four-point row.
Earning the sophistication point
Situate the argument in a broader context, engage seriously with complexity or tension, or write with consistent rhetorical control. Not achieved by longer words.
Weighing evidence against commentary
Most students give too much evidence and too little explanation. Aim for roughly twice as much commentary as quotation.
Handling a counterargument in an argument essay
Name the strongest opposing position, grant what is valid, then show why your claim still holds. Ignoring it looks like you did not think of it.
Reading period strategy
The first fifteen minutes are for reading and planning. Annotating sources and outlining a line of reasoning beats starting to write immediately.
Avoiding device-listing
Never write "the author uses anaphora and imagery." Write what those choices do to this audience given this purpose.
Nuance and qualification
A position that concedes conditions and limits is more defensible and reads as more sophisticated than an absolute one.

Practice English Lang

Our practice bank is drawn from across the whole course rather than filtered to one unit, which is closer to how the exam asks anyway — it will not tell you which unit a question is testing.
