The Polytechnic in Medical Lab Technician diploma typically lasts 3 years, and the entire programme is divided into six semesters. Each semester focuses on different areas of medical laboratory science, ensuring that students gradually build strong technical knowledge and practical skills.
During these three years, you learn about subjects like haematology, microbiology, biochemistry, pathology, immunology, and lab safety. The semester-wise structure helps students understand the topics step by step instead of rushing through them. It also allows enough time for hands-on training, practical sessions, and the use of modern laboratory equipment.
Many colleges also include internships, hospital visits, and project work as part of the later semesters to ensure real-world exposure. By the time you complete all six semesters, you are fully prepared to work confidently in laboratories, clinics, and diagnostic centres.
The Polytechnic in CSE diploma lasts for 3 years, and these three years are divided into six structured semesters. Each semester focuses on different areas of Computer Science and Engineering, allowing students to gradually build their technical knowledge and skills.
During these three years, you move step-by-step from basic computer concepts to advanced programming, networking, database systems, and emerging technologies. The semester-wise system also includes regular practical sessions, lab work, projects, and internal assessments, which help you understand every topic in a clear and organised way.
This structured duration ensures that students get enough time for hands-on learning, problem-solving practice, and developing confidence in working with software and hardware systems. By the end of the 3-year programme, you become job-ready and prepared for higher studies or direct entry into the IT industry.
The Polytechnic in Aeronautical Engineering in India is a full-time 3-year diploma programme, and the entire duration is divided into six semesters. Each semester focuses on different areas of aeronautics, starting from the basics and gradually moving toward advanced aircraft systems and technologies.
In the first year, you learn foundation subjects such as basic engineering, physics, mathematics, aerodynamics, and introduction to aircraft systems. The second year covers more technical areas like aircraft structures, propulsion systems, avionics, and materials used in aerospace. The final year focuses on advanced topics such as aircraft maintenance, quality control, safety procedures, and practical project work.
Throughout the three years, you also spend time in laboratories, workshops, simulation centres, and aircraft maintenance training environments to gain real hands-on experience. By the end of the 6th semester, you are ready for aviation-related jobs or further studies in aeronautical or aerospace engineering.
The Polytechnic in Aeronautical Engineering diploma is a three-year program that is divided into six semesters. Each semester usually lasts about six months, and it is carefully structured to balance both theory and practical learning.
In the first year, students are introduced to the basics, such as engineering mathematics, applied physics, aircraft basics, and workshop practices. This year is more about building a strong foundation, so even students coming directly after 10th can adjust to the technical subjects.
The second year focuses on more specialized aeronautical topics. You will study subjects like aerodynamics, aircraft materials, propulsion systems, and aircraft structures. At the same time, practical sessions in labs and workshops help you connect classroom concepts with real-world applications.
The final year (third year) is all about applying your knowledge. Students learn advanced subjects like aircraft systems, avionics, maintenance practices, and aviation legislation. A major highlight of this year is industrial training or internships with aviation companies, airlines, or maintenance organizations. This gives you hands-on experience and helps you prepare for jobs right after graduation.
By the end of the three-year diploma, you are not only equipped with technical knowledge but also gain skills in problem-solving, teamwork, and leadership. This structure makes the program highly effective for students who want to start their career early in the aviation industry.
