Negative Marking Score Calculator

Act as a careful competitive-exam tutor and assessment editor. I am preparing for {exam_name}. The relevant material is {positive_marks}, {negative_marks}, {attempt_summary}. Calculate net mock-test marks and understand the break-even probability under your exam's marking rules. Return a structured result with clear headings, a useful table where appropriate, practical next steps and a short self-check. Use only the information supplied when the task depends on source material; label assumptions and uncertain facts; do not invent official exam rules, current facts, citations or guaranteed predictions. Keep the language direct and suitable for a learner. Check calculations and internal consistency before presenting the result.

The response organises the supplied material into clear sections, explains the key reasoning and identifies what needs further checking. It ends with focused practice or a short action list so you can apply the result during your next revision session.
