What closes the gap is a pair of closed book habits and a schedule, described here.
Reading is exposure; memory needs production
Print moving past the eyes produces familiarity, and familiarity impersonates knowledge until the book closes. Roediger and Karpicke measured the impersonation: groups that studied by repeated exposure predicted they would outperform the practicing groups and then scored well under half as well a week later, about one in three against close to 80 percent. Reading remains the intake valve, nothing replaces it, but the retention happens in what you do at the chapter's end, not in how slowly the eyes moved through it.
The closed book minute: summarize before you may continue
Install one rule: no new section until the finished one has been summarized with the book shut, aloud or on paper, in your own words. The minute is diagnostic and corrective at once, since fluent summarizing certifies the section while stumbling marks it for a second visit now, when the fix costs a page flip rather than a week's backtrack. It also converts passive completion pressure, must finish the chapter, into units of understanding, which is the pressure that actually serves the exam.
Question the chapter the day you finish it
A finished chapter's PDF becomes a question round in the app the same evening, and the timing is the active ingredient: the replicated forgetting curve does its worst work early, so same day interrogation catches traces while rescue is cheap. Wrong answers route back to specific sections rather than to the chapter in general, which is what makes the round a reading tool and not merely a test. The mechanics live in PDF to quiz, photographs of paper books included.
Returns: the chapter is not done when it is done
A single interrogation certifies today's memory; the schedule certifies exam day's. Cards lifted from the chapter, definitions, contrasts, thresholds, enter spaced returns with gaps scaling to the horizon per the Cepeda group's measurements, and the chapter's survival stops depending on your intention to revisit it, which is the least reliable component in any study system. The craft of which lines deserve cards is its own guide.
Where this regime does not apply
Not all reading owes an exam: breadth reading and fiction earn their keep without interrogation, and drilling them would miss their point. The regime above is for reading that must survive to a test date. One plain note: the mid 30s and near 80 percent figures are the cited experimenters' results on their materials, WeSolve+ publishes no reading retention data of its own, and the honest claim is that the regime moves you between those measured groups, not to a promised score.

Why do I forget chapters I definitely read?
Exposure builds familiarity, not production: retention comes from closed book summarizing and questioning, not from slower eyes.
What is the closed book minute?
No new section until the finished one is summarized from memory: fluency certifies, stumbling routes a cheap immediate fix.
When should I quiz a chapter?
The day you finish it, while rescue is cheap on the forgetting curve; wrong answers point at sections, not vibes.
Does this apply to novels?
No: breadth and pleasure reading earn their keep without interrogation. The regime is for material that owes an exam.
Does highlighting while reading help?
As navigation for later questioning, mildly; as study, no. The effectiveness review rates it low, so mark sparsely and interrogate instead.
