Physics is 042. Chemistry is 043. Biology is 044. Online CBSE Tutors often remind students that Mathematics is 041, Applied Mathematics is 241 — and mixing up that last pair is the single most common subject-code error we see students make at FindMyGuru during LOC (List of Candidates) submission season.

Here's the full, current list, organized the way you'll actually need it: a quick lookup first, then the complete tables, then the two mix-ups that cause real problems.

Quick Reference: Most-Searched Subject Codes

Full List: Academic Elective Subjects (Group A)

This table covers the subjects findmyguru students search for most. CBSE also codes a longer list of fine-arts and performance subjects (Carnatic and Hindustani music, classical dance forms, sculpture, graphics) .

Language Subject Codes

CBSE also assigns codes to several other regional and foreign languages (Punjabi, Bengali, Sindhi, Manipuri, Assamese, Arabic, Persian, Japanese, Nepali, and others). If your school offers one of these, confirm the code directly with your school's exam coordinator — the full regional-language list runs to over 30 entries and is best cross-checked against your specific curriculum document rather than memorized from a blog table.

Skill-Based Elective Codes (Group S)

The Two Mix-Ups That Actually Cause Problems

Most "subject code" confusion isn't about looking up a number — it's about picking the wrong subject that happens to have a similar name.

Mathematics (041) vs. Applied Mathematics (241). These aren't the same subject with different codes — they're different syllabi with different question papers and different relevance to competitive exams. Applied Mathematics leans toward statistics, financial math, and data-based problems; Mathematics is the syllabus most engineering-entrance coaching assumes. If a student is targeting JEE, entering 241 instead of 041 at LOC stage is a mistake that's expensive to reverse once submitted.

English/Hindi Core (301/302) vs. Elective (001/002). "Core" and "Elective" aren't difficulty tiers — they're separate syllabi with separate literature texts. A student who's been studying from the Core textbook all year but gets registered under the Elective code will sit an exam on unfamiliar content. This happens more often than it should, usually because a form was copied from a previous year's template without checking against the current subject list.

What Subject Codes Actually Control

The code isn't just a label — it determines which question paper you get, which answer scripts go to which evaluator, and which syllabus your practicals and internal assessments are checked against. It's used at four points: LOC submission, admit card printing, answer-script evaluation, and final marksheet generation. An error at LOC stage can cascade through all four.

For the 2026-27 session, marking splits between theory and practical/internal assessment vary by subject — Physics, Chemistry, Biology, and Computer Science follow a 70-theory/30-practical split, while most non-lab subjects (English, History, Economics, Accountancy, Business Studies, Political Science) follow 80-theory/20-internal. Don't assume a flat 80/20 split applies to every subject — check your specific subject's split on your admit card or with your school.

If You Think a Wrong Code Was Submitted

Once a school submits the LOC to CBSE, subject-code changes are restricted and require formal approval routed through the school within CBSE's specified correction window — late requests are generally not accepted. In our experience guiding students through registration at findmyguru, the fastest fix is to flag the discrepancy to your school's exam coordinator the moment you notice it on your admit card draft, not after the final admit card is issued. Schools can usually still request a correction before the LOC finalizes; after that, options narrow sharply.

How findmyguru Helps With Subject Selection

Picking between Mathematics and Applied Mathematics, or deciding whether a skill elective is worth the practical workload, is a subject-choice decision as much as a code lookup — and it's easier to get right with someone who's seen how these choices play out for other students.

If you're weighing subject combinations for Class 12, you can connect with a subject-specific tutor who can walk through syllabus differences before you finalize your LOC entry — not just after something's gone wrong.
