Reviva vs interview courses: which do you actually need?

Course or AI examiner? It depends where you are in your prep. When each one pays off, and how to tell which stage you are at.

Both are useful, at the right stage. Early prep is about building your knowledge and developing a spoken style of your own through consistent practice, which is what Reviva is designed for. A course is most useful near the end, when seniors and consultants can give tailored feedback on a style you already have. It comes down to the stage you’re at and what you need to work on.

The early months: build the foundation

Most of your prep is groundwork: learning what each station actually wants, then answering out loud until your style is your own rather than something memorised.

A course can’t do much for you at this point. One day of teaching, however good, doesn’t build habits.

This stage is what Reviva is built for. A voice-based AI examiner runs the real CST and ST3 plastic surgery station formats with you, out loud and against the clock, whenever you can practise. That might be 11pm after a shift, in the browser or on the iPhone and Android apps, without coordinating anyone’s diary or calling in favours.

Not another improvising chatbot

The AI conducts the interview and will interrupt and push back the way a real examiner does, but it never invents the medicine. Every one of the 180+ stations is hand-written and mapped to the official marking criteria.

Reviva marks every attempt on the official scale, 0–5 for plastics or 0–6 for CST, and debriefs you on where the marks went. Over the weeks you can watch a weak station climb instead of wondering whether the practice is working.

The practice modes follow the same stages: drill a single station while you’re learning it, sit a surprise mock station to test yourself, or run the full multi-station circuit against the clock when you want the real thing. Three difficulty settings take the examiner from encouraging to genuinely stern.

The final weeks: bring in the humans

Once you have a style, tailored feedback sharpens it. This is where a course earns its fee. Senior trainees and consultants who have sat on real panels can react to you specifically and answer your questions live. Hearing other candidates answer also recalibrates your sense of the standard, which is hard to get any other way.

Whatever else you do, book at least one human mock before the real thing. No software replaces the judgement of someone who has actually sat on a panel.

So, where are you?

Just starting. Read the free station guides to learn what each station wants, and use Reviva to start answering out loud from day one.

Theory solid, delivery wobbly. You need repetition. A couple of stations a day, rotating your weakest ones, will move your scores faster than more reading. This is the most common bottleneck by a distance.

Final weeks. Book a course or senior mocks to refine your style, and keep up daily timed rehearsal so it stays sharp.

Not sure. Spend ten minutes on the free sample stations. Answering a real station with the timer running will tell you which stage you’re at before you’ve spent anything.

Frequently asked questions

Is Reviva a replacement for an interview course?
No. They belong to different stages of your prep. Reviva is for the months of building knowledge and a spoken style of your own through consistent practice. A course is most useful near the end, when tailored feedback from seniors and consultants refines what you have built.
Which is better value?
Depends how much you will actually practise. A course is one fee for one day. Reviva is a subscription you run only for the months you need. If you would do two mock stations and stop, the course wins. If you will practise most evenings through interview season, the maths flips quickly.
Can I do well with neither?
Yes. People pass every year on free guides and disciplined peer mocks with generous seniors. Paid options buy structure, feedback and rehearsal volume with less organising effort. They do not buy anything a well-organised candidate cannot get for free.
