Candidates spend months preparing for the viva and almost no time thinking about what happens afterwards. Then the outcome arrives — usually some form of corrections — and a stage that should take a defined number of weeks stretches out, because nobody explained how it works.
The first thing worth knowing: corrections are normal. Passing with no corrections at all is uncommon enough that it should not be your benchmark, and treating anything else as a disappointment misreads the process. Examiners are expected to find things.
The outcomes and what they mean
Terminology varies by country and institution, but outcomes generally map onto this ladder.
- Pass with no corrections. Rare. Not the standard against which to judge your own result.
- Minor corrections. The most common outcome. Typos, clarifications, a section that needs expanding, references to fix. Typically weeks, often signed off by the internal examiner alone.
- Major corrections. Substantial revision — reworking an analysis, restructuring a chapter, deepening a thin discussion — but without new data collection. Typically months, and usually re-read by both examiners.
- Revise and resubmit. The thesis is not yet at doctoral standard. A longer period, often a year, sometimes with a second viva. Serious, and a normal route to a doctorate for a meaningful number of candidates.
- Award of a lower degree, or fail. Uncommon, and rarely a surprise to anyone who has been reading the supervision record honestly.
The distinction that matters most is between corrections and resubmission. Corrections mean the doctorate is established and the thesis needs improving. Resubmission means the examiners are not yet persuaded. Those are different situations and it is worth being clear which you are in.
Working through minor corrections
Minor corrections are usually a list, sometimes annotated in the margins of a returned copy, sometimes as a formal document. The failure mode here is not difficulty but drift: the work is undemanding, the deadline feels distant, momentum has gone after the viva, and three months pass.
Treat it as a finite task with a date. Block time in the first fortnight while the viva is fresh. Most candidates who stall on minor corrections stalled because they stopped, not because a point was hard.
Working through major corrections
Major corrections need a plan, because they usually involve genuine intellectual work rather than tidying.
Start by sorting the list. Some points are structural — restructure a chapter, reframe the contribution — and everything else depends on them. Some are analytical and take real time. Some are presentational. Do the structural ones first, because rewriting prose that later moves chapters is wasted effort.
Then get agreement on interpretation before you start. Examiner comments are often shorter than the work they imply, and "the discussion does not adequately engage with the wider literature" could mean two paragraphs or a rewritten chapter. Ask your supervisor how they read it; where it is genuinely ambiguous, most institutions allow a clarifying question to the internal examiner. That conversation is far cheaper than doing the wrong amount of work.
The correction log
Whatever the scale, build a table. This is the single most useful thing you can do, and most institutions require something like it anyway.
One row per examiner point, with four columns: the point as the examiners wrote it, what you did about it, exactly where the change is (page and section in the revised thesis), and a brief note on your reasoning where it is not obvious.
This serves three purposes. It stops you losing points buried in a paragraph of prose. It gives the examiners a document that lets them verify your work in an hour instead of re-reading the thesis, which materially speeds up sign-off. And it forces you to confront every point rather than quietly skipping the awkward ones.
When you disagree with an examiner
You are allowed to disagree. You are not allowed to ignore.
If you believe a point is mistaken, respond to it in the log with a reasoned argument rather than silently declining to act. "We retained the original analysis because the assumption of proportional hazards was tested and met (see Appendix C, p. 214); we have added that test explicitly at p. 118 to make it clear" is a legitimate response, and a well-argued one is often accepted.
Two cautions. Pick your battles — disputing many points reads as defensiveness and makes the reasonable disagreements harder to hear. And discuss it with your supervisor first; they know the examiners and the institutional norms, and they can tell you whether a particular objection is worth making.
If you are resubmitting
Revise and resubmit is the outcome candidates find hardest, and the one most often misread. It is not a fail. It is an extended deadline with a specification attached, and a substantial number of people who receive it go on to be awarded a doctorate.
Practically: take a short break first — a week or two — because starting a year of revision while demoralised rarely goes well. Then get maximum clarity on what is required, in writing, and confirm your reading with your supervisor. Agree a supervision schedule for the revision period; this is exactly when contact tends to lapse and exactly when it matters most. Find out whether a second viva is expected, and whether the same examiners will re-read.
And keep the perspective right. The examiners have told you what a doctorate requires and given you time to produce it. That is a considerably better position than most people assume when they first read the letter.
