Yes. Every completed sitting is recorded — not only your best and not only your most recent — and each one stays for 65 days from the day you sat it before it is removed automatically.
Two clocks run across a Premium purchase and they are easy to run together. One is the access period, which decides whether you can still open the exam at all. The other is retention, which decides how long a finished attempt survives, and it is measured per attempt from the sitting itself rather than from your purchase or your activation. Neither is a version of the other.
What Is Kept After a Networking Practice Session Ends
Nothing is thinned out on your behalf. A sitting that went badly is kept beside one that went well, and the attempt you would rather forget is kept beside the one you would rather be judged on. The list belongs to the exam rather than to the account, and since the full-length session, the mini and the demo are three separate exam pages, each keeps its own list and you reach it from there.
That is the point of keeping all of them. A single log entry read on its own tells you very little, because nothing in it says whether the event it recorded began the fault or followed from it. Line the same window of logging up across the devices either side, which only works where they are keeping the same time, and the order becomes readable. A run of attempts behaves the same way, and it only exists because nothing was discarded for you in between.
