About this tool
Frame physics, chemistry and maths doubts so AI explains step by step, with JEE Main time and negative-marking maths built in.
This builder frames a JEE physics, chemistry or maths doubt as a step-by-step teaching prompt: it names your exact confusion (concept, method choice, stuck mid-solution, answer mismatch or speed), applies a subject-specific solving framework, and forbids skipped steps. Alongside, it shows the JEE Main arithmetic that shapes practice — 2.4 minutes per question and the +4/−1 marking scheme under which even a blind four-option guess carries +0.25 expected marks. Built for JEE Main and Advanced aspirants using AI as a doubt-solving tutor.

Physics gets free-body diagrams and dimensional checks; maths gets domain-first rigour; chemistry gets mechanisms and exceptions.
Five doubt types produce five different prompts — a concept gap and a speed problem need opposite explanations.
Time per question and the full guessing expected-value table under +4/−1 marking, computed, not asserted.
State the subject and level, paste the full question, name what exactly confuses you, and demand one step per line with every formula named before use. Adding your own attempt matters most — it turns a generic solution into a diagnosis of your specific error.
Statistically yes, once you can eliminate anything: under +4/−1 with four options, a blind guess averages +0.25 marks, one elimination raises it to about +0.67, and two eliminations to +1.5. These are long-run averages though — on a single question a wrong guess still costs a mark.
2.4 minutes on average — 75 questions in 180 minutes. Strong candidates bank time on their best subject and spend it on multi-step numericals, but any single question crossing 4-5 minutes is usually a signal to mark it and move on.
Treat them as a tutor's first draft, not an answer key: language models make sign errors, drop constants and occasionally invent formulas. Verify each step against NCERT or your standard text, and prefer prompts that force symbol-first algebra and a dimensional check, which make errors easier to catch.
