How the Random Study Topic Picker works

Under the hood, this calculator is intentionally simple. There’s no AI, no hidden server and no data collection. Everything runs in your browser using a lightweight formula that combines three ingredients: your chosen subject, your focus style and your time block.

Each subject category (Math, Science, History, Languages, Computer Science, Business and Mixed) has a curated mini-library of classic study topics. These are things like “Algebra – linear equations”, “Biology – cell structure” or “World history – key revolutions”. When you pick a subject, the calculator narrows the universe down to only topics that match that lane.

Your time slot and focus style tell the calculator how “heavy” the topic should feel:

• Short blocks (15–30 minutes) bias towards tighter tasks: definitions, flashcard-type concepts or very small sections.
• Medium blocks (45–60 minutes) unlock slightly bigger topics: a full chapter section, a past paper section or a mini project task.
• Long blocks (90+ minutes) are where deep dives and multi-step topics appear: several related subtopics bundled into one session.

Your focus style (quick review, deep dive, past papers, flashcards) is used to flavor the text, so the suggestion feels like an actual plan instead of a vague title.

The Study Focus Score is a playful scorer, not a scientific metric. It takes the subject code, time block, focus style and a small random element based on the current time. All of that is mashed into a number between 0 and 100. Higher scores appear when:

• You give yourself a reasonable time block for the topic.
• The focus style matches the type of content (e.g., past papers for exams).
• The random “momentum boost” rolls in your favor.

The progress bar updates instantly so your brain gets a tiny “game bar” feeling. Even though it’s just math, it makes the choice feel more real and easier to commit to.

• Whenever you feel stuck choosing a topic, open this page and spin once.
• Set a timer for the time block you picked and follow the suggestion.
• If you still feel restless, spin again – but only after completing at least one focused block.
• Take screenshots of fun or ultra-high Focus Scores and share with friends for accountability.

Random Study Topic Picker – FAQs

• Is this random, or does it follow a pattern?

  It’s a hybrid. The calculator uses your subject and time inputs to choose from a small list of relevant topics, then adds a random element so you don’t always see the same suggestion. If you refresh, you might get a different topic for the same settings – that’s on purpose.

• Is the Focus Score scientifically accurate?

  No. The Focus Score is a playful number that blends your time, subject, style and a random “motivation” boost. It’s there to make your choice feel more like a game, not to measure your real attention span or mental health. Treat it like a fun nudge, nothing more.

• What if the topic doesn’t match what I actually need to study?

  Use your judgment first. If the suggestion is way off from your upcoming exam or assignment, tweak the subject or time and spin again. You can also treat the suggestion as a warm-up: do 15 minutes of the random topic, then switch back to your main study plan.

• Can I use this for multiple subjects in one day?

  Absolutely. Many students like to rotate: do one spin for Math, one for Science, one for History, etc. As long as you keep sessions short and focused, this can turn a long revision day into bite-sized blocks instead of a giant overwhelming task.

• Does this store my data or require login?

  No login, no signup, no AI and no server-side processing. Your spins are generated in your browser, and the optional “Save Spin” feature uses local storage on this device only. Clearing your browser data will remove saved spins.

How to make this go viral

Because this tool runs instantly in the browser and looks good in both light and dark mode, it’s built to be screenshot and reel friendly. A few ideas to spark virality:

• Record a “Study With Me” reel where you spin the topic picker at the start of each pomodoro.
• Challenge friends: “Spin this once and you have to study whatever comes up for 30 minutes.”
• Share ultra-high Focus Scores (90+) as “exam mode unlocked” screenshots with your own caption.
• Use it during live streams to let chat vote on whether you respect the spin or reroll.

The more you treat the result like a game mechanic instead of a serious exam prophecy, the more likely people are to share, laugh and come back.
