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. |

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 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.
