No — DBExam works out nothing of the kind. It does not calculate a readiness score, weigh your chances of passing, or predict how you will fare on the actual Oracle exam. What remains once those are ruled out is the record itself — each sitting’s score and its explained review — and reading readiness from that record is a judgement it leaves with you.
It would be easy to want a single number that reads ready or not ready. The platform prints none, and the reason it declines is the honest core of this answer.
No Readiness Score Sits Behind Your Oracle Results
The platform keeps an exact account of what happened on each sitting — the tally, the percentage, the marked-up review — and it goes no further than that account. It puts no probability on your passing, distils your sittings into no single verdict, and stamps no ready-or-not label on your history. Any such number would have to assume that the real Oracle exam draws and behaves like a practice sitting, and that a percentage earned here carries cleanly to exam day; neither is a promise worth making, so it is not made. The 100% Money-Back Guarantee is a separate thing with conditions of its own and a page of its own — a promise about refunds, not a reading of your readiness.
What Tells You You Are Ready for the Oracle Exam
Readiness is a call you make yourself, off your own record. Sit Premium full-lengths across your Oracle track and the evidence builds in a form you can weigh: a percentage that stops swinging and settles high across several sittings; a review in which an optimiser item on column histograms — the sort you kept misreading — finally goes in cleanly. That is you judging the evidence, sitting by sitting, rather than a meter judging it for you, which is exactly why the confidence you reach is real and not borrowed from a figure on a screen.
So DBExam puts no estimate on your readiness and makes no forecast about the real exam: it gives you honest scores and an explained review, sitting after sitting, and leaves the verdict on whether you are ready with the only person placed to reach it — you.

No. There is nothing in your account that resets a score or clears your history, and no single attempt can be picked out and deleted — a sitting, once recorded, is not something you can take back out. What empties the list instead is the retention running out on each attempt, which happens on its own.
Look through your account settings for a reset or clear-all and you will come up empty; the list holds firm until its own retention lets go, so the useful thing is to mark out where the boundary actually falls.
What You Can and Cannot Do with an Oracle Attempt
What you can do is open any finished sitting and read it again, as often as you like, for its score and its full review — and that is the whole of it. You cannot edit a score, pull a single sitting out of the list, or hide one from view, and there is no reset tucked into your account settings. A first SQL mini on which an aggregate slipped into the SELECT without a GROUP BY — the ORA-00979 you now catch on sight — is logged exactly as you sat it, low score and all, and it cannot be scrubbed to lift the way the list reads.
Why the List Only Changes on Its Own
Because nothing you do removes an attempt, the list moves for a single reason: each sitting eventually runs its retention out and is cleared for you, on the automatic schedule the attempt-history page describes. Until an attempt reaches that point it stays exactly where it is; once it does, it is gone, with nothing required from you and no warning given. There is no quicker route, and none was ever built in — the list settles itself in time rather than on your say-so.
So DBExam keeps no reset switch and no clear-all, and no attempt of yours is editable or removable: your Oracle sittings stand as you took them and leave the list only when their retention lapses — cleared for you, never by you.

Yes — every sitting you finish is logged, and the one thing that ever takes an attempt off the list is its own 65-day clock reaching zero, at which point the system clears it automatically. Short of that the record is left untouched: no older run is dropped to make space and no attempt is cut short of its window, so on the Demo and on Premium alike the full set of your sittings stays there to reopen.
What one of those entries actually holds is the first thing to pin down; exactly how long it survives is the second, and that one has a firm, single answer.
What Your Oracle Attempt History Records
Each entry is one completed sitting, and it stays openable: you can bring any of them back for its score and another walk through the review. You can tell the sittings apart at a glance — a full-length run reads differently from a mini, and both from a Demo — and read the score each earned alongside whether it came out Passed or Failed once measured against the exam’s standard. It is a running log rather than a curated best-of: an Oracle Data Guard full from a fortnight ago sits in the same list as a SQL mini from this morning, the shaky attempts kept with the rest, because the point of the record is the sequence and not a highlight.
How Long Each Oracle Attempt Survives
The figure is a flat 65 days for every attempt, counted from the sitting itself. Each one carries its own expiry from the day you sat it, so records drop off singly, each on the day its own clock runs out, instead of the list emptying all at once. When an attempt reaches its 65th day the system takes it out — not you, and with no prompt beforehand — and it does not return. Inside that window nothing is thinned to make space, so whatever you have sat in the period is there in full to reopen. The one thing you cannot do is clear an attempt ahead of that schedule by hand, which is a limitation with a page of its own.
All told, DBExam does keep your Oracle history — every completed sitting, its score, its verdict and a way back into the review — for 65 days apiece, then clears each attempt automatically as it ages past the window, with nothing pruned early and nothing left for you to tidy.

Yes, on the free Demo and on Premium alike. Bring a finished sitting back from your history and every question you were set returns for study, each one anchored — where an explanation has been written for it — by an account of what makes the correct option correct; ranged around that are the item as it stood, the choice you made set against the right one, and every option marked in turn.
The distance between a mark and a lesson is the why behind the correct answer, and that why is the half that shifts your next sitting. The review attaches it to each question and plays them back in the order you met them.
What the Oracle Review Puts in Front of You
Pull a completed sitting back up and it takes you through question by question, each option marked and your own pick set beside the key. Take a PL/SQL item on exception handling that offers, among its choices, a block closing with WHEN OTHERS THEN NULL; pick it and the review crosses it, marks the option that lets the exception surface as the one to have taken, and then does what a bare mark cannot — it explains that a handler ending WHEN OTHERS THEN NULL catches every error only to discard it, so the failure you needed to see slips by in silence. That is the reasoning behind the key, not merely the fact of it. The choices come back in the very order you faced them, because the platform keeps the order you saw and plays it back rather than shuffling anew — the mechanism behind it is set out on Are the Questions Randomised?
Reviewing Your Oracle Sitting on Either Tier
None of this is held back for paying users: the Demo opens the same review Premium does, so you can weigh the feedback before spending anything. Nor is it a one-time glance — every sitting stays in your history and reopens into the identical walk-through for as long as the attempt is kept, so an attempt from earlier in your preparation is still open to pick apart days later. What it is not is a scoreboard of your strengths and gaps: there is no panel ranking you by Oracle topic, leaving you the items themselves, the marking and the written reasoning, and the work of seeing the pattern yourself.
So yes — after any Oracle sitting every question is yours to revisit, the Demo giving you the same review as Premium, with each option marked, your choice against the key, and a written reason for the answer, as often as you reopen the attempt. The one thing the review will not hand you is a verdict on which topics you have mastered; that reading stays yours to make.

Yes, though the right way to read that screen is for the score rather than a verdict. The instant an Oracle sitting is marked it declines to call the attempt Passed or Failed and puts no rating on how ready you are — both are kept off the screen by design. What it does hand you is the plain result: the count right out of those asked, that count again as a percentage, and the full review opening straight off it.
Where readers trip is in expecting that screen to declare a pass or a failure. It does not, and the reason is worth a moment, because the pass-or-fail label is real — it simply lives one place over.
The Score and Review an Oracle Sitting Ends On
When the clock stops, your score appears at once in two forms: the plain count of items right out of those asked, and the percentage they come to. Beside that sits the entrance to the review, where every question of the sitting reopens for study. It reaches no further than that total, though: it does not split the result across the exam’s topics to show which corner of the Oracle material let you down, and it puts no figure on your readiness for the real exam. Those are left, in turn, to the review itself and to a page of its own.
Where Your Oracle Attempt Gets a Pass or Fail
The Passed and Failed wording does exist, but it belongs to your list of attempts rather than the screen you meet on submitting. There, each recorded sitting carries a label of its own, worked out by holding your percentage against the pass standard Oracle sets for that credential. That standard is not one fixed figure across the board: Oracle pitches it per exam, so a score that clears an Oracle Database SQL paper need not clear a database administration one. Because the raw screen has no way to know which bar applies until the attempt is filed, the verdict can only be settled in the history, where the comparison actually takes place.
So every Oracle sitting ends the same way — a tally, a percentage and the full review, delivered the instant you submit — with the screen itself stopping short of any pass or fail. That label waits in your attempt history, judged against the standard for your particular Oracle exam, and the question of readiness waits further on again.
