Questions and answers

Who makes CivilPrep?

CivilPrep is an independent practice course built around the Civil Service Success Profiles behaviours published on GOV.UK. Every scenario is original and written for this course.

What do the scenarios cover?

Workplace situations and case study developments that train four published behaviours: making effective decisions, working together, communicating and influencing, and delivering at pace.

How are my answers marked?

Each action is rated on the four-point scale of the official test: Effective, Partially effective, Ineffective or Counterproductive. Your score shows how closely your judgements match our expert key, and the explanation shows exactly why.

When do Fast Stream applications close?

Applications for 2027 entry are open from midday on 8 October 2026 until midday on 5 November 2026, UK time. The online tests come after you apply, so every practice session keeps paying off.

Can I try it before I buy?

Yes. The free practice test gives you 20 full scenarios with explanations, and you do not need an account.

Is there anything to pay on top of the price?

No. The launch price of £39 is the whole price: one payment for 12 months of access, no subscription and nothing added at checkout.

What are the Fast Stream online tests?

Two tests, published on Civil Service Careers: work-based scenarios, where you rate the effectiveness of several actions in 12 scenarios, and the case study assessment, with 7 pieces of background information followed by 24 situations. Our online tests guide covers both.

Are the online tests timed?

No. The tests are untimed and take around one and a half hours in total, and you have 7 days to complete them from the moment they open. CivilPrep mocks run untimed like the real tests, or timed at that 90-minute pace.

What does the full mock include?

6 full mocks, each in the official order: 12 work-based scenarios, then a case study with 7 background documents and 24 situations. You get your score by section, by behaviour and by question style, with every answer explained, plus a personal plan that spaces the mocks up to your date.
