How we write, check and correct.

Who writes what you read

Our guides and data pages are drafted with software we built. Before a page is published it goes through our automated publishing checks, which look for claims we cannot back, stale prices, and a new page that would compete with one we already have. Every editorial post names the person responsible for it. The generated marks, rank and percentile pages say "Compiled by PrepGraph · data reviewed by" the person who checks the data behind them, and link to our methodology.

Where our facts come from

We use sources in this order, and link the one we used:

1. The exam bodies. NTA for NEET-UG and JEE Main (nta.ac.in, neet.nta.nic.in, jeemain.nta.nic.in), MCC for NEET counselling (mcc.nic.in), College Board for the SAT and PSAT, and ACT for the ACT.
2. Their own documents. Information bulletins, result notices, score-release schedules and seat-allotment documents, read at the source and linked from the page that uses them.
3. Our own data. Where a page shows figures we computed, such as a rank estimate from a percentile, it says so and shows the working. How we build those pages is on the methodology page.

We do not use results or counselling aggregator sites as a source for new pages, and we are replacing the few older citations to them with the official documents.

Keeping dates and figures current

Exam dates, patterns and counselling schedules change every year, and some change round by round. We check a page's facts against the official source when the next cycle is announced. Where a schedule moves too often to repeat safely, such as counselling rounds or score-release dates, the page sends you to the official schedule instead of copying a date that will expire. Each guide and data page shows the date it was published, and the date it was last updated if it has changed since.

Estimates are estimates

Rank predictors and percentile-to-rank pages give ranges built from past years' official data. They are for planning, not promises: your official scorecard and the counselling authority's own lists decide. We never guarantee a score, a rank, a seat or an admission.

Corrections

If you find a mistake, write to support@prepgraph.com with the page's address and what is wrong. We correct factual errors, and the guide's "Updated" date shows when it changed.
