Stable calculations and changing rules are stored separately so a correct formula does not make an old visa, scholarship, admission or credential requirement look current.
Research hierarchy
We prefer government immigration portals, ministries, official study portals, universities, recognition authorities, scholarship providers, licensing boards, credential issuers and formal standards. Secondary sources can help discover a question, but high-impact claims should resolve to the responsible authority.
Knowledge graph
Countries, institutions, programmes, scholarships, qualifications, grading systems, language tests, visa rules, costs, deadlines, recognition authorities, professions and credentials are treated as connected entities. This lets one verified fact support the right tools and pages without copying the same claim into unrelated templates.
Calculations and estimates
Tools distinguish official thresholds from estimates, label assumptions, avoid claiming admission probability where no published rule supports one, and avoid presenting grade or qualification comparisons as formal equivalency decisions.
Freshness
Source-backed records show a verification date. High-volatility areas such as visa funds, work rights, dependants, post-study routes, deadlines and scholarships require more frequent review than stable mathematical converters.
