An app that allows you to prepare for cognitive function tests
This is an app for the cognitive function test you take when renewing your driver's license. Those aged 75 and over must pass this cognitive test. *A doctor's certificate is required if you score below 36 points. Use this app to prepare and aim for a high score. Repeated practice tests will yield the best results. Updated and updated as of May 2022. With the in-app purchase (low price) displayed on the second round, all tasks A-D become available, and ads are removed. Even if you absolutely want to use it for free, you can use it to the end by watching ads. *You don't need to install the ad app if you simply close it!
