Teachers who have graded multiple rounds of essays on "The Plague" tend to notice the same handful of mistakes recurring year after year, regardless of grade level or the specific prompt assigned. Recognizing these patterns in advance lets a teacher build preventive instruction into the unit rather than only correcting the same errors after the fact, essay by essay. Some of these mistakes are specific to this novel's particular content, while others are more general writing weaknesses that this text simply tends to surface especially clearly because of its philosophical density.

The single most common mistake is confusing Camus' absurdism with straightforward pessimism or nihilism, treating the novel's bleak setting as evidence that the text argues life has no value at all. This misreading usually stems from students encountering the plague's devastation and assuming the philosophical conclusion must match the emotional tone, without recognizing that Camus explicitly builds his philosophy around meaningful action despite, not because of, that bleakness. Addressing this mistake requires direct vocabulary instruction early in the unit, since students genuinely cannot write accurately about a distinction they have not yet learned to make.

A second frequent error is treating the plague purely as a literal disease narrative rather than engaging with its allegorical dimensions, which produces essays heavy on plot summary and light on interpretation. This happens most often when students have not been given explicit permission or instruction to read the novel allegorically, since some students default to the most literal reading available unless a teacher signals otherwise. A brief historical note about Camus writing during the Nazi occupation of France, and the novel's original French publication in 1947, often unlocks this allegorical reading for students who were previously stuck at the surface level.

Mistakes in Evidence Selection and Use

Beyond conceptual misunderstandings, students frequently make evidence-related mistakes, such as choosing a quote because it contains a keyword related to the essay's theme rather than because it genuinely supports the specific claim being made. A student writing about isolation might quote any passage mentioning separation or quarantine without checking whether that particular passage actually illustrates the specific kind of isolation their argument addresses. Teaching students to ask "does this quote prove my exact claim, or just something in the same general topic area" as a check before including evidence helps address this pattern directly.

• Confusing absurdism with nihilism or simple pessimism instead of understanding Camus' distinction
• Reading the plague only literally, missing its allegorical connection to occupation and moral crisis
• Selecting quotes for keyword relevance rather than genuine support of the specific claim being made
• Overusing plot summary in place of analysis, especially in essays about character development
• Ending essays with pure restatement rather than genuine synthesis or broader implications

Structural and Organizational Mistakes

Organizationally, one of the most common patterns is a chronological essay structure that simply follows the novel's plot from beginning to end rather than organizing around distinct analytical points. This tends to produce essays where the fifth paragraph is not meaningfully different in kind from the second, just further along in the story, which signals the student has not yet separated argument structure from narrative structure in their own thinking. Explicitly teaching students to organize by idea rather than by chronology, perhaps by having them outline their argument points before deciding which scenes to discuss, helps break this habit.

Conclusions are another persistent weak point, with many student essays simply restating the thesis in slightly different words rather than offering genuine synthesis or broader significance. A stronger conclusion on this novel might connect the specific argument back to Camus' broader philosophical project, or note an implication the essay's analysis raises but does not fully resolve. Modeling this kind of conclusion explicitly, showing students the difference between restatement and genuine synthesis using a real example, tends to improve this weak point more reliably than simply telling students to "avoid repeating yourself."

Building Prevention Into the Unit Design

Because these mistakes are so predictable across multiple cohorts of students reading this novel, the most efficient intervention happens before the essay is assigned rather than after it is submitted. A short diagnostic exercise early in the unit, asking students to define absurdism and revolt in their own words, can surface conceptual confusion while there is still time to correct it through direct instruction. Similarly, a low-stakes practice paragraph focused specifically on evidence selection, graded only for whether the quote genuinely supports the stated claim, can catch that pattern before it appears in a formal graded essay.

Teachers who track these common mistakes across multiple years of teaching the same novel often find it worthwhile to build a short handout or checklist specifically addressing them, distributed alongside the essay prompt itself. This kind of proactive resource tends to reduce the overall grading burden, since fewer essays arrive with the same predictable, correctable errors that would otherwise require identical feedback comments across dozens of papers. Over time, this approach shifts a teacher's grading time away from repeatedly flagging the same basic issues and toward providing the more substantive, individualized feedback that actually helps advanced students continue improving.
