We test tools against the original formula or rule wherever possible, then check edge cases so the result is understandable to a student using the tool under real pressure, such as placements, admissions, or scholarship applications.

• Academic conversion tools are checked against board or university regulations, not only generic web formulas.
• Salary-related tools are reviewed against current public tax and statutory deduction guidance before material updates go live.
• If a tool produces a simplified estimate, the surrounding copy is expected to say so clearly and link to the broader methodology page.

Tool accuracy depends on the original rule set. For that reason, we prioritize source owners such as boards, universities, and government departments over third-party explainers.

• University regulations and grading policies

  CGPA, GPA, and academic calculators are checked against university or board-issued rules before release or revision.

• Income Tax Department and Finance Act guidance

  Salary and tax tools are reviewed against active Indian tax rules before material updates go live.

• EPFO and public compliance guidance

  Used for PF-related assumptions and salary-breakdown explanations where statutory rules matter.
