## What is Tes Kraepelin?

Authentic Kraepelin and Pauli practice, with the real timing and scoring.

Train on the Kraepelin test (answered bottom to top) and the Pauli test (answered top to bottom) with a precise per-column timer, then read a full breakdown — Speed, Accuracy, Consistency and Endurance — alongside your work curve and what it means.

The Kraepelin and Pauli tests are timed mental-arithmetic assessments used in recruitment and psychological screening. The task is simple and relentless: add two adjacent digits and write only the last digit of the sum, over and over, against the clock.

KEY FEATURES
• Two authentic tests — Kraepelin (upward) and Pauli (downward), with the original mechanic.
• Precise per-column timer with auto-advance, exactly like a real answer sheet.
• Four psychometric scores: Speed, Accuracy, Consistency and Endurance, plus a WORK CURVE and its interpretation.
• History and trends: track all four scores, your best result and a daily streak.
• Daily Challenge to keep a consistent practice habit.
• Custom Practice: set your own column count, seconds per column and difficulty.
• PDF sheet generator, so you can practise on paper too.
• Learn section explaining how each test is scored.

WHO IT'S FOR
Anyone preparing for an aptitude or concentration test as part of a hiring process, and anyone who simply wants to sharpen mental arithmetic, focus and sustained attention.
