Never miss SAQs for mids,semester exams and Viva in Applied Physics
Ace Your Applied Physics Vivas, Mids and Semesters! (Part A Essentials)
Hey B.Tech Superstars! ✨
Are you a B.Tech student aiming to conquer your exams?
Gearing up for your Applied Physics mids, semester exams, or even those tricky viva voce (both internal and external labs)?
Are you from CSE, IT, CSIT, or specialized branches like CSE(AI&ML), CSE(DS), CSE(CS), AI&DS, CSE(Networks), CSE(IOT), CSD, or maybe from ECE, EEE, MEC, EIE, ME, AE, BT, MIE, or PCE?
Feeling like Applied Physics is throwing curveballs? 😵💫
You're in the right place! Applied Physics is a fundamental subject for all first-year B.Tech students, regardless of your department. Scoring well starts with mastering the basics, and that's where Part A questions come in. These short-answer questions are crucial for building a strong foundation and are often the key to nailing your mid-term exams and viva sessions.
Why focus on Part A? They test your quick recall, understanding of definitions, principles, and key concepts. They are the building blocks for the more complex problems in Part B.
Ready to boost your preparation? Here’s a curated list of unique Part A questions compiled from previous JNTUH Applied Physics papers, arranged unit-wise as per the latest syllabus:
