I have been taking a practice test every single day, but I feel like I am just memorizing the questions now. Is this counterproductive? How often should I be taking full-length exams to actually measure my knowledge versus just remembering the answers?
Practice exams should be taken no more than once per week to ensure learning is based on conceptual mastery rather than rote memorization of question patterns.

To optimize your retention and ensure your diagnostic accuracy, you should adopt a structured cycle of study and evaluation:
- Limit full-length practice exams to a frequency of once every seven days to prevent memory contamination.
- Dedicate the intervening days exclusively to deep-dive review of the domains where your performance is statistically weakest.
- Maintain a log of incorrect responses to ensure that future testing measures comprehension rather than recall.
You are absolutely wasting your time by grinding tests daily. Once you start recognizing the patterns of the questions, you have crossed the threshold from active learning into rote memorization, which provides a false sense of security that will fail you during the actual audit of your skills.
Back when I was prepping for my CISM, I fell into the exact same trap of hammering practice banks every night after a long shift at the SOC. I thought the volume was helping, but I realized about two weeks in that I was just subconsciously checking boxes because I remembered the wrong answers were distractors, not because I understood the underlying risk management principles.
I had to force myself to stop cold turkey for five days, switch over to reading the primary documentation, and then return to the practice exams as a diagnostic tool rather than a study guide. Once I treated the exam as a way to find where my documentation knowledge was thin rather than a way to pad my confidence, the real test became significantly easier to navigate.
Taking a test every day creates a bias in your data because you are measuring your ability to recall the source material rather than your ability to apply the concepts to novel scenarios. If your goal is to pass, daily testing is inefficient, but if your goal is to actually learn the material, it is counterproductive. You have two options here: use the test as a raw assessment tool or use it as a learning aid, but they function differently.
Testing once a week is better if you want a reliable score that predicts your real-world performance, as it gives you enough time to perform remedial study on the gaps you identified without the interference of short-term memory. However, if you use a test as a learning aid, you should instead focus on taking small sets of 10 or 20 questions immediately after studying a specific topic, which allows for immediate feedback. The trade-off is simple: longer intervals provide a more accurate baseline, while frequent targeted testing accelerates the absorption of technical details. You should aim for a cadence that allows you to address the root causes of your errors rather than just logging your score, which is essentially just vanity metrics that will lead to a failure in the field.
