Letter cancellation d · b · q · p
Find exactly the right signs among many similar ones – as in concentration tests for school, training and job applications. On screen or on paper. ← All concentration exercises
How it works
Pick a level
Easy: every d (good against mixing up b and d). Medium: every d with exactly two marks. Hard: the same with 15 seconds per row.
Cross out
Tap the targets, a second tap takes it back. At the end you see hits, overlooked targets and wrongly crossed signs.
Worksheets with 8 to 14 rows, fields for name, date and time – and, if you like, a solution sheet with the targets circled.
Frequently asked questions
How does the exercise work?+
Rows hold the letters d, b, q and p with small marks above and below. You look only for the d with exactly two marks – both above, both below or one above and one below. All other signs stay. Well-known concentration tests work in a similar way.
Is this the d2 test?+
No. The d2-R is a standardised psychological test by a publisher and is evaluated by professionals only. This exercise is built in a similar way and is meant for practice and getting to know the task – it gives no norm values and no test score.
What do the errors mean?+
Overlooked targets often show haste or a moment of inattention, wrongly crossed signs imprecise looking. Together they make the error count; the time shows the pace. With practice most people get both faster and more accurate.
Is it suitable for children?+
Yes, the Easy level without marks already suits primary school children and helps against mixing up b and d. For children and older people there is “Extra large print” when printing.
How do I print several sheets with solutions?+
Open “Worksheets to print”, pick level and number, keep “Solution sheets” ticked and tap “Print / save as PDF”. Every sheet is new; the solutions come at the end with the targets circled and the number of targets per row.
The exercises are for practice and fun. They do not replace a diagnosis or therapy.
