Over testing happens when you keep taking exams back-to-back without learning from them. Writing too many tests without proper review can hurt more than help. You end up measuring performance repeatedly instead of actually improving it.
Follow a simple cycle: attempt, analyse, revise, then retest. The analysis stage should take more time than the test itself. That’s where real progress happens. Without it, the same mistakes repeat.
Also protect your mental energy. Fatigue lowers accuracy and confidence. One well-analysed test each week is far more effective than several rushed attempts. Use tests for correction, not just for counting scores.
