SRM Semester 4 subjects, syllabus units and exam plan — all 10 subjects mapped.
Semester 4 continues core CSE with DBMS, DAA and AI. DAA builds directly on DSA from Semester 3 — a strong DSA foundation is essential. DBMS is the most-asked subject in non-tech placement interviews (analyst, consulting roles).

CGPA importance in Semester 4
DBMS and DAA are both placement-critical. Companies test SQL queries (DBMS) and algorithm design (DAA) in every interview. Target 8.0+ in both.
Semester 4 study tips
- Practice SQL queries daily — joins, subqueries and normalization are interview staples
- DAA dynamic programming problems overlap with LeetCode medium/hard questions
- AI search algorithms (A*, minimax) are fun to implement and interview-friendly
- Start building a mini-project using DBMS concepts for your resume
