Practice guidance

    
• Begin at a level where you can explain most solutions after reviewing them.


• Read the explanation even after a correct answer; a sound method matters more than a guess.


• If you miss a pattern repeatedly, open its lesson and work through the example.


• Increase difficulty after consistent success, not after a single correct answer.

    
Your answers and saved progress stay in this browser. Analytics may count trainer interactions, but never records answers or saved progress.

Frequently Asked Questions

              

              

                How do I use this trainer?
                
Choose a difficulty, select an answer, and check it. Review the explanation before moving to the next exercise, and use the linked lesson when a concept needs more attention.

              

              

                Are my answers or progress sent anywhere?
                
No. Answers and saved progress stay in this browser. Analytics may count controlled interactions such as starting or completing an exercise, but it does not include answers, free text, notes, or saved progress.

              

              

                What changes between difficulty levels?
                
Higher levels use more steps, rules, items, or distractors, depending on the exercise type. They may also provide less time. You can change the level at any point.

              

              

                Does the score measure intelligence or predict performance?
                
No. Accuracy and streak describe your activity in this trainer only. They are not standardized, diagnostic, or suitable for making educational, employment, or clinical decisions.

              

              

                Where is my progress saved?
                
Progress is saved in this browser for this specific trainer. Clearing site data or using another browser or device starts a separate progress record.

              

              

                When should I use hints and explanations?
                
Try the exercise first, then use a hint if you cannot identify a productive next step. After checking the answer, compare your method with the explanation even when you were correct.
