How to study from lecture slides: your notes beside each slide

What students say works with slides (one person's view each)

These are replies from four Reddit threads, read in full on November 5, 2026. Each is one person's experience, not research, and they disagree with each other. The board fits the part they agree on: don't just reread.

• Say it, then check it. In r/PAstudent (2022), a top reply goes through the topic list out loud in simple terms, then looks at the slide, and writes down anything missed or wrong. That list becomes a study guide of what didn't stick. That is the own-words card and the red card.
• Don't just summarize. In r/NoteTaking (2025), the poster says summarizing slides in a notebook never produced useful exam notes. One reply says they now rephrase key points in their own words and add examples or questions. Another says slides are part of a bigger picture and suggests drawing coloured arrows between two ideas.
• Rewrite, don't copy. In r/StudentNurse (2022), one reply says to handwrite notes and another says you are rephrasing into shorthand, not copying every slide. A third says to understand the material instead of memorizing it.
• Divide a slide into subsections. In r/GetStudying (2024), a reply splits each slide into subsections such as characteristics, clinical findings and management, and fits 10 or more slides onto one A4 page of mind map.

Others in the same threads prefer flashcards, practice questions or reading the slides several times. The board doesn't replace any of that; it is a place to do the rewrite-and-question step.

How to use the board

1. 1Open the board and sign in free to edit. Set the focus card at the top to the lecture's question.
2. 2Put a slide in each blue card's place. Paste or add a picture of the slide, or type its key line. Remember the limit: 3 images per board on the free plan.
3. 3Write the slide in your own words on the green card. Not a copy of the slide: what you would say to someone who missed the lecture.
4. 4Write what you can't explain yet on the red card. If it is empty, you may be done with that slide.
5. 5Add margin notes with the pen in the grey section: a mnemonic, the page of the textbook, what to ask the lecturer.
6. 6Before the exam, scan the red cards. They are the part of the slides you haven't got yet.

The board is a layout, not a tool that checks your answers. The elasticity example on the ready board is a typed stand-in so you can see the pattern.

The 3-image limit, and what to do about it

The free plan allows 3 images per board and 1 file per board. Slides are usually pictures, so this is the main limit for this use.

• Pick the 3 slides you struggle with and type the key line of the others onto cards. A typed card counts toward the 150-item account limit; an image counts as one too.
• One board per lecture. Each board counts toward your 5 free boards, so this works for a few lectures, not a whole course.
• Pro has no image limit. Pro is $5 a month billed yearly ($59.99), or $7.99 monthly.
• Import PDF is not the way to bring in a slide deck right now. Don't plan around it.

From slides to an exam study guide

Once you have your own-words cards, the same board can become an exam study guide. These steps paraphrase the University of Toronto Scarborough's "Create an Exam Study Guide" page (read November 5, 2026), which suggests working from the syllabus, lecture slide titles and chapter titles, and from what your professor repeated or emphasized.

1. 1Make an exam-details card. Course, exam date, how much it is worth, the question types, and what you need to know (definitions, graphs, worked examples). The board has an example in purple. Ask your professor if you can't tell.
2. 2List the topics and rank them by importance. UTSC suggests judging this by how long your "focus on" list is and which topics your professor spent the most time on; you can also ask which topics are worth more marks. On the board this is the blue list: most marks first.
3. 3Write one "focus on" line per topic. This is the part you don't yet understand well, so it comes straight from your red cards.
4. 4Check yourself by explaining it. UTSC says that if you can't explain a topic to someone else concisely, it needs more time. A study group is one place to do that.
5. 5Cross topics off as you get confident, and start with the most important ones.

The Rutgers Learning Centers' "Tips for Using Study Guides" (May 19, 2023; read November 5, 2026) says to make your own guide before looking at the one your professor gives you, then compare the two. Anything in theirs that is missing from yours, or that you don't understand, is a topic to review.

Study groups: one board for the group

The UNC Learning Center's study group handout (read November 5, 2026) says students find groups help them "externalize their thoughts", keep sessions stimulating and keep each other accountable. It adds that groups work best small enough for everyone to ask and answer questions, and suggests a facilitator, ground rules such as taking turns asking and answering, and meeting about once a week for 60 to 90 minutes. For groups that meet online it names Zoom, Microsoft Teams and GroupMe, and suggests looking for online versions of what you miss, such as a whiteboard.

• Split the lectures. The study group list on the board has a task per person: lectures 1 to 3, lectures 4 to 6. Each posts their 3 hardest slides as new rows.
• Answer each other's red cards. The last task on the list is to answer one red card from someone else. That is the group's active-study step.
• Share the link, or use the code for a live session. A new board starts view-only for people with the link; choose "Anyone with the link can edit" in Share to let the group write. A 4-digit join code expires after 2 hours of inactivity.
• Each member signs in free to write. Each member's board count includes boards opened from a link, so a member at 5 boards can still open it but the app says it won't be added to their boards.
• Call on the board. Free calls run up to 60 minutes per call, with a warning 10 minutes before the end. Everyone needs a free sign-in; calls aren't recorded.

Ask members to put their first name on their cards. There is no roster, per-person view or grading.

When something else is the better choice

• You want a summary written for you. AI summarizers and study-guide makers read your slides and produce notes. We don't. If that is what you want, you will be disappointed here.
• You want to annotate the PDF itself. Notes apps built for marking up PDFs let you write directly on the slide pages; one r/PAstudent reply imports the slides into Notability and takes notes on them. Instaboard doesn't import PDFs as a working path right now.
• You need spaced repetition. Anki and Quizlet schedule cards for you. The board has no flashcards or scheduling.
• You need practice questions. Several replies stress them. Use the ones your lecturer or a question bank provides.

What this board doesn't do

• It doesn't read, summarize, search or grade slides. No text recognition, no handwriting search.
• Writing needs a free sign-in. Viewing a shared board doesn't.
• The free plan is 5 boards and 150 items per account (cards, lists, images, text boxes; pen strokes, sections and arrows don't count), with 3 images and 1 file per board.
• Written for adult learners and students 13 and older. Instaboard's terms say users are not minors.
