5th Semester: The Year Where Your Career Takes Shape
By the 5th semester you are more than halfway through your diploma. Now subjects become less about "studying" and more about "building". With Java you will build real applications, with IoT you will connect hardware to code, and with electives you will decide which direction to go — mobile apps, security, or networks.
This is also the updated NEP-2020 curriculum for 2026-27. The total is 550 marks — but note that the 100 marks of qualifying subjects are not included in this. Total 20 credits, L12 P16.

* (Q) means qualifying — passing is compulsory, but these marks are not added to your percentage or division.
What Is In Each Subject
1. Java — Object Oriented Programming
The biggest subject of the semester — the Classes and Objects unit alone is worth 30%. Classes, constructors, inheritance, packages, abstract classes, interfaces, polymorphism, exception handling and multithreading — everything. There are 12 practical programs: a bank Account class, an Employee hierarchy, a Shape hierarchy and a thread program. A student who gets comfortable with Java finds placement coding rounds much easier.
2. Internet of Things (IoT)
IoT means connecting everyday things to the internet — smart homes, health monitoring, agriculture. Units: Introduction to IoT, IoT Devices (sensors, actuators), IoT Networks, Arduino, and IoT vs M2M. The practicals are entirely on Arduino: LED blink, LDR night lamp, temperature sensor (LM35/DHT11), LCD display, air quality sensor (MQ135), Bluetooth (HC-05) and relay-based home automation. These practicals give you an understanding of hardware that theory alone never can.
3. Program Elective-2 — Your Choice
Two options: Mobile App Development (Android, Android Studio, activities, intents, SQLite, publishing on the Play Store) or Multimedia Technologies (compression — JPEG, MPEG, MP3, MP4 — Photoshop/GIMP, Blender, animation). Both are worth 5 credits. Find out in advance which option your college offers — not every polytechnic offers both.
4. Program Elective-3 — Your Choice
Two options: Information Security (cryptography, PKI, network security, digital signatures) or Advance Computer Networks (telecom networks, QoS, network simulation, router configuration). For students heading into security, Information Security is the direct route.
5. Open Elective-2 And Indian Constitution — Qualifying, But Do Not Ignore Them
For Open Elective-2 you choose one of Product Design, Engineering Economics & Accountancy, or AI and Machine Learning (TATA) — or an Advance Skill Development certification of at least 20 hours. Indian Constitution is an audit subject. The marks do not count towards your percentage, but passing is compulsory — so treating them as "small subjects" and skipping them can cost you dearly.
Internship-II — 6 Weeks, 100 Marks
The 6-week internship after the 4th semester is evaluated in the 5th semester. Report, presentation and viva — this is the experience you will talk about in placement interviews. Choose an internship connected to your elective: an app company if you are learning Android, a network/security place if you chose security.
Practical Advice For The 5th Semester
Write Java code every day — OOP is never understood by reading alone. Build one small IoT project yourself, like a temperature display or switching a light on/off over Bluetooth — that project goes on your resume. Before choosing an elective, ask your seniors which subject has the better lab and faculty in your college. And start writing your internship diary from day one.
