AKTU B.Tech 1st Year Subject Codes 2026-27: ACS, AAS, Engineering & AI Courses Explained
Searching for an AKTU B.Tech 1st-year subject by its code is often faster than searching by the full subject name. The 2026-27 CSE Stream curriculum uses course identifiers such as ACS101 and AAS103D, while subject pages and college notices may use shortened names.
This guide maps the important first-year subject codes to their subjects and links them to the detailed GyanAangan syllabus pages.
Why AKTU Subject Codes Matter
Subject codes are useful when checking college timetables, examination forms, internal assessment notices, practical schedules and syllabus PDFs. A search for a code can also avoid confusion when two subjects have similar names.
Important AKTU B.Tech 1st-Year Codes
| Code | Subject | Area |
|---|---|---|
| AAS103D | Calculus and Linear Algebra | Basic Science |
| ACS101 | Programming Languages | Engineering Science / CSE |
| ACS201 | Essentials of Data Structure | Engineering Science / CSE |
| AAI101 / AAI201 | Introduction to AI & Prompt Engineering | AI / Engineering Science |
Course combinations can vary according to the applicable branch and scheme, so treat this table as a navigation guide and confirm the final subject combination against the official scheme supplied by AKTU or your college.
Calculus and Linear Algebra — AAS103D
AAS103D is the code used on our detailed guide for Calculus and Linear Algebra. It is a 4-credit Basic Science Course in the first-year structure.

How to Check Your Exact Branch Combination
The first-year CSE Stream contains alternative courses for different branches. Therefore, two students may see different choices even though both are searching for the AKTU first-year syllabus.
- Identify your exact B.Tech branch.
- Open the applicable AKTU first-year CSE Stream scheme.
- Match the course code on your college timetable or examination notice.
- Use the subject-specific guide for unit-wise preparation.
- Use your college's latest notice if a branch-specific option is listed.

Final Note
Subject codes are useful for finding the correct syllabus quickly, but always match the code against your current AKTU scheme and college timetable. The safest workflow is code → official scheme → subject guide → unit-wise preparation.
How These Codes Connect to the Semester Structure
The subject code is only one part of the syllabus. The same first-year CSE Stream guide contains theory courses, laboratory courses, skill/project work and non-credit mandatory components. This is why a timetable can contain a mixture of code-based subjects and entries such as Language Lab or General Proficiency.
Semester I
Semester I includes the higher-credit mathematics and programming components alongside science, engineering and professional courses. The detailed Semester I guide is the better page to use when you want the complete timetable-style structure.
Semester II
Semester II introduces Essentials of Data Structure and Numerical Methods alongside the remaining first-year components. See the Semester II guide for the subject-by-subject breakdown.
Subject Code Search Tips
- Search the exact code in quotation marks when using Google.
- Combine the code with AKTU 2026-27 to reduce results from older schemes.
- Check the semester before downloading a PDF.
- Match the code against your college timetable before preparing from a third-party summary.
- Prefer the latest official scheme if two pages show different course combinations.
