The CRA Holland code describes candidates who lean primarily Conventional with strong secondary Realistic and tertiary Artistic traits. Below: what this means in plain English, the 8 Nigerian university courses that match the profile best, and how to use the code with your JAMB strategy.
What CRA means in plain English
People with a Conventional lead are typically organisers, structured, detail-oriented people. Add a strong realistic pull (the second letter) and a tertiary artistic side (the third), and the CRA profile describes someone who blends those three orientations in roughly that order of strength.
Strengths. Attention to detail, organisation, comfort with rules and structure, preference for measurable outcomes. The realistic layer adds: practical skill, mechanical aptitude, comfort with tools and physical work, preference for tangible outcomes.
Common challenges. May find ambiguous, fast-changing work uncomfortable; benefits from clear structures and measurable goals. May find purely abstract roles or heavy bureaucratic environments draining without hands-on outlets.
Treat your three-letter code as a useful summary rather than an identity. Most undergraduates' profiles shift through university and the first few years of work; revisit the quiz in a year or two.

Career paths for CRA candidates
CRA candidates typically thrive in roles that combine the three orientations in the order shown. The dominant conventional layer points toward structured, data-oriented or administrative roles.
The realistic secondary layer reshapes those roles. For example, an SI profile (Social-Investigative) suits clinical medicine; an IS profile (Investigative-Social) suits research-driven healthcare like public health and epidemiology. Both involve health, but the day-to-day balance of patient contact versus analysis differs.
How to use your Holland code with JAMB
Use it as one of four signals. Combine the CRA interest profile with: your academic stream (science / arts / commercial), your JAMB readiness (UTME score and subject combination), and your practical preferences (region, fees, study duration). The /what-to-study quiz on this site blends all four and produces a shortlist of 5 courses with the universities that fit your score.
For JAMB candidates with a clear CRA profile but no decided course, start by treating the top 3 matches above as primary options. Use their course pages to confirm the UTME and O'level subject combinations, then plan your JAMB strategy around those subjects.
