How to Practice for a Viva by Yourself (When You Have No Reader)

The limit of solo prep, and how to push past it

How to practice for a viva by yourself is a real question because a reader who has read your thesis, knows the field, and has ninety minutes free is hard to find. Supervisors read chapters. Colleagues read for style. Neither always sits and asks the questions an examiner will ask.

Solo practice has a real limit: without a reader, there is no follow-up. A real examiner does not accept a first answer and move on. They push. Solo prep covers the answer, not the pressure. That said, three techniques close most of the gap, and each one costs nothing but time.

Technique 1: Read a passage aloud, then ask the question the passage invites

The single most useful solo technique is anchored self-questioning. Pick a page of your thesis. Read the passage aloud. Then ask yourself, in one sentence, the question the passage would invite from an examiner. "You claim on page 47 that these two frameworks are compatible. Say more."

Write the question on a card. Move to another page. Repeat. Build twenty to thirty questions across the chapters, prioritising the methodology chapter and the findings chapter. These are the passages examiners spend the most time on (Trafford & Leshem, 2008).

The technique works because it forces you into the examiner's reading position. You are no longer reading what you meant to write. You are reading what is on the page. That shift catches the passages where a claim rests on something you cannot immediately recall, or where a chapter ends without connecting to the next.

Technique 2: Record yourself answering

Record your answer to each question. Use your phone. Play it back the same day. Note where you drifted, hedged, reached for filler, or spoke for two minutes when the answer needed thirty seconds.

The record-and-play method is widely recommended by university viva preparation guides (Vitae; Edinburgh IAD). There is no formal published efficacy study, but the mechanism is clear: hearing yourself under examination conditions exposes weaknesses that the writer's own memory smooths over. Rehearsing under recording conditions moves the same weaknesses closer to the surface, where you can fix them.

The move that matters most is not the recording itself, it is the playback. Candidates who record and never play back stay in the writer's-eye view. Candidates who play back move into the examiner's-eye view.

Technique 3: The why-asker chain

The third technique is the why-asker chain. After you answer a question aloud, ask "why?" out loud. Answer that. Ask "why?" again. Chain the questions until you either reach a defensible foundation or notice that your answer is running out of support.

Real examiners do this. The first question sounds gentle. The follow-up presses harder. The third or fourth follow-up is where the argument either holds or collapses. Rugg and Petre (2004) describe this as one of the "unwritten rules" of doctoral vivas: the panel is testing not what you know, but where your reasoning runs out.

Solo, you can push the chain further than a live rehearsal would. There is no reader to interrupt. Take an answer, ask why, and keep going until you notice the point at which the answer needs work.

Where solo practice hits its ceiling

Solo practice does two things well: it exposes weaknesses in the writing and it trains the answer pattern. It does one thing poorly: it does not create the pressure of an unfamiliar reader who has spent hours with your thesis and will not accept a rehearsed line.

That is where the ceiling sits. If you have a colleague in the field who has read the thesis, invite them for a rehearsal. If you have a second supervisor, activate that channel. If you have neither, the specific gap is filled by Thesisroom's defense practice, which reads the thesis and generates examiner-grade questions anchored to specific passages. Each question shows the page it came from. Answers are scored on clarity, depth, and accuracy. It is not a live examiner, but it is closer to one than a generic viva question list.

A weekly solo-practice schedule

Six weeks before the viva, run solo practice on a weekly cadence.

• Week 6: Read the thesis end to end. Mark passages that would invite questions. Build the first twenty questions.
• Week 5: Answer the first ten questions aloud. Record and play back.
• Week 4: Answer the next ten. Add the why-asker chain to five of them.
• Week 3: Rehearse the one-minute contribution answer until you can deliver it without notes.
• Week 2: Full solo run: answer 20 questions in sequence, record, play back, mark weakest three.
• Week 1: Rehearse the three weakest. Rest.

This structure is not a rule; it is a shape. Adjust for the time you have. What matters is that solo practice runs weekly rather than as a single crammed day.

What Thesisroom does with this

Thesisroom's defense practice reads the thesis or a single chapter and generates examiner-grade questions anchored to specific passages. Each question includes the page reference. Answers can be typed or spoken, and are scored on clarity, depth, and accuracy against the source text.

The full method treats rehearsal as a whole-degree seat. Chapter-level rehearsal runs during the writing months; full-thesis rehearsal runs in the final weeks. The tool does not replace a live colleague-examiner rehearsal where you can get one. It fills the specific gap when you cannot.

Frequently asked questions

How much solo practice do I need before a viva?

At least six to eight weekly sessions of 45 minutes to 90 minutes, plus one full-length rehearsal in the final two weeks. Solo practice does not scale linearly (more is not always better), but under-practice is the more common failure. Candidates who do fewer than four practice sessions tend to walk into the room less settled.

Is recording myself really useful?

Yes, but only if you play the recording back. The value is in hearing yourself the way an examiner will hear you: pace, filler, hedges, the moments where you drift. Recording without playback stays inside the writer's-eye view and does not produce the shift solo practice is meant to create.

What questions should I practice with?

Questions drawn from your own text, not generic viva question lists. Generic lists rarely produce useful practice because examiners rarely ask them in generic form. Anchor each question to a specific page of your thesis, and rehearse the answer with the page in front of you.

Can I practice with a colleague who is not in my field?

Yes, and it helps for basic clarity and pacing. A colleague from an adjacent field can catch when your explanations assume too much specialist vocabulary. What they cannot do is press on the technical specifics of your methodology or findings; that is where an in-field reader (or an anchored tool) is needed.

How is Thesisroom's defense practice different from a generic viva question list?

Generic lists are the same for every candidate. Defense Practice reads your thesis and generates questions anchored to specific passages. Each question shows the page it came from. That is closer to what an examiner actually does, because examiners' questions come from the specific text of your thesis rather than a public list.

Should solo practice replace a mock viva with a real reader?

No. If you can arrange a mock viva with a colleague or a second supervisor, do. Solo practice is the daily habit that keeps the answer pattern sharp; a live mock viva is the pressure test that solo practice cannot fully replicate. Both work best together.

One takeaway before you close this tab

Solo viva practice is anchored self-questioning, recorded answers played back, and why-asker chains that push each answer to its foundation. When the ceiling of solo practice is reached and no live reader is available, Thesisroom's defense practice generates anchored questions from your own thesis and scores your answers against the text.
