Free forever · No card · 9,000+ questions

Different modes wire different memory.

Each family targets a distinct cognitive lever: recognition, pattern, recall, fluency.

Classic

Recognition

  • Multiple Choice

    Single best answer from four choices. The default loop — fast and dense.

    10Q
  • True / False

    Rapid-fire true or false statements. Great for drilling definitions and busting misconceptions.

    10Q

Pattern

Categorization

  • Odd One Out

    Four items, three belong together, one doesn't. Trains categorization instincts.

    10Q
  • Binary Blitz

    Pro

    One expansion shown, one hidden. Is the visible one correct — or is it the other one?

    20Q
  • Blind Pick

    Pro

    One answer revealed, one hidden. Is the visible option right — or take your chances with the mystery?

    15Q

Recall

Retrieval

  • Fill in the Blank

    Pro

    Type the missing term, command, or concept. SRS-eligible — sticks long-term.

    8Q
  • Fill Blank · Acronym

    Pro

    Given an acronym, type the missing word(s) of its full expansion from memory.

    10Q

Acronym

Fluency

  • Acronym Expansion

    XSS? MITM? SSRF? Pick the real expansion from four plausible options.

    10Q
  • Excluding Word

    Pro

    Three words belong to the acronym — one is an intruder. Which doesn't fit?

    10Q
