## How ThatClaude scores, criterion by criterion

| Criterion | ThatClaude (0 to 5) | Cred Farmer | Why ThatClaude scores this |
| --- | --- | --- | --- |
| Certification coverage | 4 | 5 | All four tracks exist, but the depth is one exam's: CCA-F has a 10,000+ bank while the other three list one mock-sized set each. |
| Structured learning | 4 | 5 | A curriculum, handbook, glossary and quick reference, described as a full curriculum on CCA-F. Not 5: no labs or exercises are published. |
| Taught delivery | 0 | 0 | Written material only. |
| Practice depth | 4 | 5 | 10,000+ domain-mapped items with explanations on CCA-F, most of them generated variants from a parametric generator, and a mock-sized set on each other track. Deep on one exam, thin on three: 4 rather than 5. |
| Mock-exam realism | 3 | 5 | One full-length timed paper per track at the real item count, scored 100 to 1000. |
| Diagnostics and personalisation | 3 | 5 | A diagnostic, a per-domain breakdown after each sitting, and a spaced-repetition drill to route you back, on CCA-F. |
| Retention system | 4 | 5 | A spaced-repetition drill across the CCA-F syllabus; the algorithm is not published, so not 5. |
| Evidence and transparency | 4 | 4 | Independence stated, a named author, a verification date against the exam guide, and a statement that no item reproduces real exam content. |
| Value and access | 4 | 4 | Free and complete, but a free account is required to see your score and explanations after a sitting. |
| Team and operational readiness | 0 | 3 | No team feature is published. |

| Certifications covered | All four tracks, under the CCA-F name for the architect foundations exam.  Evidence “All four tracks — CCA-F, CCAR-P, CCAO-F, and CCDV-F — are live today”  ThatClaude, read at [https://thatclaude.com/](https://thatclaude.com/) |
| --- | --- |
| Practice questions | A 10,000+ bank for CCA-F, built from hand-authored items, seed items and a parametric generator; the other three tracks list one mock-sized set each (60, 53 and 63 items) and publish no bank size.  Evidence “10,000+ question bank”  ThatClaude, read at [https://thatclaude.com/certifications](https://thatclaude.com/certifications). The about page describes the bank as merged from hand-authored scenario questions, seed questions and 'a deterministic parametric generator that produces thousands of provably-correct computed and matching questions'. |
| Study material | A curriculum, a handbook, a glossary and a quick reference; the CCA-F track is described as a full curriculum with a diagnostic and a spaced-repetition drill.  Evidence “full curriculum, diagnostic, and spaced-repetition drill”  ThatClaude, read at [https://thatclaude.com/certifications](https://thatclaude.com/certifications) |
| Full-length timed mocks | One timed mock per track at the real item count and 120 minutes, scored on a 100 to 1000 scale.

| Diagnostics | A diagnostic on CCA-F, and a score with a domain breakdown after each sitting.  Evidence “to view your score, domain breakdown, and explanations once you finish”  ThatClaude, read at [https://thatclaude.com/about](https://thatclaude.com/about) |
| Readiness / adaptive path | Not published |
| Free tier | Everything is free.  Evidence “Every practice mode, the full mock exam, the diagnostic, the glossary, and the quick reference are entirely free — there's no paywall, no ads, no upsell.”  ThatClaude, read at [https://thatclaude.com/about](https://thatclaude.com/about) |
| Price | Free, with no paid tier.  Evidence “there's no paywall, no ads, no upsell”  ThatClaude, read at [https://thatclaude.com/about](https://thatclaude.com/about) |
| Account required | Yes, to see a score, the domain breakdown and the explanations after a sitting; the sitting itself needs none.  Evidence “you only need a free account (email sign-in via Clerk, a third-party auth provider) to view your score, domain breakdown, and explanations once you finish”  ThatClaude, read at [https://thatclaude.com/about](https://thatclaude.com/about) |

## Which to choose

### Choose ThatClaude if…

- You are sitting the architect foundations exam and want an effectively unlimited free bank to drill.
- You want a diagnostic and spaced repetition on that exam without paying.

Choose Cred Farmer instead if the cases in [its own entry](https://credfarmer.com/compare/methodology#cred-farmer-evidence) fit you better.

### What ThatClaude does not offer

- Depth is on one exam: the other three tracks list one mock-sized set each and publish no bank size.
- Much of the large bank comes from a parametric generator producing computed and matching variants rather than authored scenarios.
- A free account is required to see your score, domain breakdown and explanations after a sitting.
- One mock per track, so a second fresh sitting is not available.
- No video and no instructor.
