Turn Reading Notes into a 15-Minute Flashcard Review Session

A short review session works better when you decide what to recall before starting the timer. Take a small section of notes, rewrite it as questions with precise answers, import those pairs into Flashcard Maker, and use Pomodoro Timer to keep the session bounded. The aim is to discover what you cannot yet recall, then save that work for the next session.

The 15 minutes in this guide are a suggested session plan, not a promise to master a topic in that time. Preparation may take longer, especially when the source is unfamiliar or poorly structured.

Choose a small learning target

“Review the chapter” is difficult to finish. “Distinguish image file size, pixel dimensions, and file format” is specific enough to test.

For this worked example, use these three statements:

A byte limit measures encoded file size. Pixel dimensions describe width and height in pixels. Renaming a PNG file with a JPG extension does not convert its contents.

These are original demonstration notes. They are intentionally short so the card construction is visible. For your own subject, select a few ideas from material you are allowed to reuse and keep the source nearby for checking answers.

Step 1: Get readable text, if you need it

If the notes are already plain text, start with them. If they are inside a supported PDF or office document, Extract Text can provide a plain-text starting point.

Review the extracted words against the original. Column order, symbols, headings, and broken lines can need correction. An extraction tool does not decide which statements are worth learning or whether an answer is scientifically or historically correct.

The current text extractor does not perform OCR on image-only scanned PDFs. A photo of a textbook page is therefore not interchangeable with a PDF containing usable text. If the source is a scan, obtain readable notes through an appropriate separate process before following this workflow.

This extraction step is optional. Adding a tool between already readable notes and your cards only creates more work.

Step 2: Make each card test one decision

Turn the notes into questions that you can answer before looking at the back. A card should make the intended answer clear enough to judge.

Weak front	Better front	Why it helps
Images	What does a byte limit measure?	One explicit concept
Explain dimensions and formats and compression	What do pixel dimensions measure?	One manageable answer
PNG/JPG	Does renaming PNG to JPG convert it?	Tests a specific misconception

Avoid putting an entire paragraph on the back unless the task genuinely requires a long explanation. A long answer makes it easy to remember one phrase and mistakenly mark the whole card as known.

If the subject requires reasoning, include a small application question as well as a definition. For example: “An image is below the byte limit but has the wrong width. Which property still needs checking?” The answer is pixel dimensions, not another arbitrary reduction in JPEG quality.

Step 3: Import a small deck and verify it

Open Flashcard Maker, choose Import, and paste the following text pairs:

What does a byte limit measure? | Encoded file size
What do pixel dimensions measure? | Width and height in pixels
Does renaming PNG to JPG convert it? | No

The current importer accepts Front | Back pairs as well as supported CSV, tab-separated text, and exported JSON. For these simple lines, the separator is unambiguous. If your card text itself contains separator characters or commas, use a properly escaped supported format rather than guessing how a complicated row will be parsed.

After importing, check the number of cards and open each one. Confirm that the front and back have not been swapped and that punctuation has not split a row incorrectly.

Imports append to the current deck. They do not replace it. Clicking Import again with the same material can create duplicates, so check whether the first import worked before repeating it.

For this guide, an empty deck became three cards. We exported JSON and independently checked that all three questions and answers were present, with their known markers initially false. That verifies this small import/export path; it does not measure learning outcomes.

Step 4: Set a bounded review session

Open Pomodoro Timer. A practical suggested plan is:

Part of the session	Suggested activity
First 2 minutes	Check the deck and recall the topic without looking at notes
Next 9 minutes	Answer cards before revealing them; mark difficult items honestly
Final 4 minutes	Rewrite ambiguous cards, retry missed items, and export a backup

These are planning allocations, not measured completion times. Use a shorter or longer session if it better fits the subject or your attention.

Set Focus to 15 minutes. If the large countdown still displays the previous duration, pause and reset the current timer, then confirm it reads 15:00 before pressing Start. In our interface check, changing the setting alone did not replace the existing countdown; Reset applied the selected duration.

Keep the timer tab open. Browser sleep and background behavior can affect alerts, so do not treat a browser timer as a critical alarm. We verified setting, starting, pausing, and resetting the session; we did not run a complete 15-minute learning experiment for this article.

Step 5: Use recall rather than recognition

In Study mode, read the front and say or write the answer before flipping the card. Space flips and arrow keys move between cards in the supported desktop workflow. If the answer is visible too soon, recognition can feel like knowledge without testing whether you could retrieve it unaided.

Quiz mode provides Reveal answer and the Again, Good, and Easy choices. Use those labels as feedback about the attempt you just made. Do not describe them as a guaranteed long-term spaced-repetition schedule or a scientific mastery score.

When you miss an answer, identify why:

• You did not know the fact.
• The question was ambiguous.
• The answer contained several independent facts.
• The source explanation was incomplete or incorrect.

Those problems need different fixes. Repeating an unclear card more often does not make its wording clearer.

Step 6: Save the deck somewhere you control

Export JSON before changing browsers, clearing site data, or moving devices. Local autosave is convenient, but it is not a cloud backup.

The current tool stores cards in this browser profile's localStorage, which is not encrypted storage. Do not put passwords, recovery codes, or sensitive personal records into a study deck. The export contains card text and known markers; it does not preserve a running quiz session as if you had frozen the whole page.

To restore a supported export, paste the complete JSON into the import area. Remember that imports append. Keep a named backup such as image-basics-cards.json and verify the resulting card count when restoring it.

What makes this a repeatable workflow?

At the end, you should have a small deck with checked answers, a record of which questions were difficult, and a saved export. The next session begins with those artifacts rather than another search for a flashcard service.

If preparation consumes the whole session, reduce the scope. Three carefully worded cards that you actually test are more useful than a large imported deck whose answers you have not checked.
