SRM Semester 4 PYQs, notes, syllabus and subject resources — 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).

Database Management Systems (DBMS)
ER model, relational algebra, SQL, normalization, transactions and concurrency.
Design and Analysis of Algorithms (DAA)
Divide and conquer, greedy, dynamic programming, backtracking and NP-completeness.
Artificial Intelligence (AI)
Search strategies, knowledge representation, reasoning and machine learning basics.
Probability and Queueing Theory (PQT)
Random variables, distributions, Markov chains and queueing models.
Internet of Things (IoT)
IoT architecture, sensor networks, communication protocols and cloud integration.
Digital Image Processing (DIP)
Image enhancement, filtering, segmentation, morphology and compression.
Advanced Programming Practice (APP)
OOP patterns, multithreading, collections, GUI programming and unit testing.
Foundation of Data Science (FDS)
Data wrangling, exploratory analysis, statistical inference and visualization.
Probability and Applied Statistics (PAS)
Probability, sampling, hypothesis testing, regression and ANOVA.
Electronic System and PCB Design
PCB workflow, schematic capture, layout, routing and design for manufacturing.
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
