FAQ
Common questions about the JEE Main score calculator.
How does this compare to the eSaral marks calculator or Mathongo score calculator?
AlphaJEE uses the same input (your NTA Response Sheet) and the same scheme (+4 / -1 / 0 for unattempted) as eSaral and Mathongo. The difference is that AlphaJEE runs entirely in your browser, never asks for an email or login, and loads in under 200 ms. The answer keys are the official NTA final keys post-challenge — identical to what eSaral and Mathongo use.
What is the JEE Main marking scheme?
Standard JEE Main: +4 marks per correct MCQ, -1 mark per incorrect MCQ, 0 for unattempted, and 0 for incorrect numerical answer (no negative marking on numerical type questions).
Are the answer keys the official NTA ones?
Yes. AlphaJEE has 30 shifts loaded with NTA's final answer keys (post objection-and-challenge round). These are the same keys eSaral, Mathongo, and every other reputable tool uses. Source: official NTA.
Does AlphaJEE store my response sheet?
No. Parsing and comparison happen entirely client-side in your browser. Nothing is sent to a server. Refresh the page and the data is gone.
