Every semester, students searching for VTU maths notes run into the same confusion: is it BMATS101, 22MATS11, or 18MAT11? Are BMATS201 and 22MATS21 the same subject? The honest answer is that these codes represent the same underlying subjects — Engineering Mathematics 1, 2, 3 and 4 — under different VTU curriculum revisions, and using the wrong one can mean revising topics that aren’t on your actual syllabus, or missing topics that are. This guide clears up exactly which code applies to you and why it matters.
Why VTU Has Multiple Codes for the "Same" Subject
VTU periodically revises its curriculum scheme — adjusting module content, sometimes adding or removing topics, and renaming subject codes to reflect the revision year. Students admitted in different academic years follow different schemes, which is why your friend one year ahead or behind you may have a completely different code for what sounds like the same subject.
The Current 2022 Scheme
Under the 2022 scheme, Engineering Mathematics 1 is coded BMATS101 at most colleges, though some institutions use 22MATS11 as an equivalent designation for the same subject and scheme year. Engineering Mathematics 2 follows the same pattern: BMATS201, with 22MATS21 as the equivalent code some colleges use. If you enrolled recently and aren’t sure which applies, check your college’s official timetable or result card — the code printed there is authoritative, not what a forum or a friend tells you.
The 2018 Scheme
Under the earlier 2018 scheme, the equivalent subjects are coded 18MAT11 (Engineering Maths 1) and 18MAT21 (Engineering Maths 2). Students who began under this scheme, or who are repeating a subject from an earlier admission year, should search specifically for 2018-scheme resources rather than assuming 2022-scheme notes cover identical content — module content and emphasis can differ meaningfully between scheme years, even when the subject name looks the same.
Branch-Specific Variants — BMATE101, BMATC101 and Others
Within the same 2022 scheme, some colleges assign a branch-specific variant of the Engineering Maths 1 code rather than the general BMATS101 — BMATC101 for CSE-stream sections at certain colleges, BMATE101 for EEE-stream sections, following the same “Differential Calculus and Linear Algebra” core content but numbered to match the enrolling branch. If your result card or timetable shows a code ending differently from BMATS101 but the subject name still reads “Engineering Mathematics 1,” this branch-specific numbering is almost always the explanation — the underlying syllabus is the same core Engineering Maths 1 content, just coded per branch rather than universally.
Older and In-Between Codes You Might Still See
17MAT11 appears for students under an earlier 2017 scheme revision, predating even 18MAT11 — genuinely rare today but still relevant for students repeating a subject from several years back. If you see 22MATS21 specifically (rather than BMATS201) for Engineering Maths 2, treat it as fully equivalent — some colleges simply prefer the “22MATS” numbering convention over the “BMATS” one for the same 2022 scheme.
Why Getting the Code Right Actually Matters
Downloading or studying from the wrong scheme’s notes isn’t just inefficient — it can mean spending real revision time on a topic your actual paper won’t test, while under-preparing for a topic that’s genuinely on your syllabus but wasn’t covered in the notes you found. Before relying heavily on any single set of notes, confirm the scheme and code match what’s on your college’s official syllabus document.
Which Guide Applies to You
Whichever code applies to your Engineering Maths 1 subject — BMATS101, 22MATS11, or 18MAT11 — the core module structure across current VTU schemes is genuinely similar: differential calculus, partial differentiation, integral calculus, differential equations, and linear algebra. See the complete Engineering Maths 1 module-wise guide →
For Engineering Maths 2 (BMATS201, 22MATS21, or 18MAT21): Laplace transforms, Fourier series, Fourier transforms, Z-transforms, and numerical methods. See the complete Engineering Maths 2 module-wise guide →
Frequently Asked Questions
Q: Is BMATS101 harder than 18MAT11?
Neither is inherently harder — they cover largely similar core techniques, with some differences in emphasis and topic ordering reflecting the scheme revision, not a change in overall difficulty.
Q: I don’t know my scheme code — how do I find out?
Check your college’s official result card, your admission year’s curriculum document, or ask your department office directly — this is the one detail worth confirming from an authoritative source rather than guessing.
Q: Do Engineering Maths 3 and 4 also have multiple codes?
Yes, following the same scheme-year logic — and unlike Maths 1 and 2, Maths 3 and 4 content also varies more by branch, since not every branch continues with identical core mathematics in later semesters.
