Use it as a starting point
Try the questions before revising. That gives you a more useful picture of what you can recall independently, rather than what feels familiar while reading notes.
How to get more from MCQ practice
Do not only look at the final percentage. Review why an answer was right or wrong, note the topic behind the question, and then test yourself again later without looking at the explanation. This turns question practice into revision rather than just a score.
If you want a larger practice set, TDNSC also offers a separate 120-question MCQ resource with different questions and saved attempts inside My Revision.
