PSBTE 1st Semester: The Questions That Repeat Almost Every Year (All Subjects)
If you’re doing a PSBTE diploma — Automobile, Mechanical, Civil, Electrical, or any other stream — your 1st semester subjects are identical: Basic Electronics, Basic Electrical Engineering, Chemistry, English, Engineering Drawing, Applied Maths, Physics, and a handful of others. We went through every available past paper for each subject and counted exactly how many times each question has actually been asked. Some have come up 13 times in the last decade.
Below is a real sample for every 1st semester subject. The full ranked top 20 for each (with solutions) is one free login away.
Basic Electrical Engineering (BEE)
“Discuss Kirchhoff’s voltage law” — 13 times. “State and explain Faraday’s laws of electromagnetic induction” — 12 times. See all 20 most repeated BEE questions →
Chemistry (CHEM)
“What are functions of lubricants?” — 13 times. “Difference between thermoplastic and thermosetting plastics?” — 10 times. See all 20 most repeated Chemistry questions →
Physics (PHY)
“Differentiate between n-type and p-type semiconductors” — 12 times. “What are the different modes of transfer of heat?” — 11 times. See all 20 most repeated Physics questions →
Basic Electronics (BE)
“Explain the working of a bridge rectifier” — 11 times. “Give construction and working of MOSFET” — 10 times. See all 20 most repeated BE questions →
English & Communication Skills-1 (CS-1)
“Define Communication? What are essentials of communication?” — 5 times. See all 20 most repeated CS-1 questions →
English & Communication Skills-2 (CS-2)
“Give the life sketch of Dr. Abdul Kalam” — 4 times. See all 20 most repeated CS-2 questions →
Computer Fundamentals & IT (CFIT)
“What are the functions of an Operating System?” — 4 times. See all 20 most repeated CFIT questions →
Environment Studies (ES)
“What is Air Pollution? Explain its causes, effects and how it can be prevented” — 4 times. See all 20 most repeated ES questions →
Engineering Drawing (ED)
Repeats here are more about question type than exact wording (drawing/projection tasks), but the same patterns come up year after year. See the ranked ED questions →
Applied Mathematics-1 & 2 (MATH-1, MATH-2)
Numerical and MCQ-style questions dominate, so it’s the problem types that repeat rather than identical wording. MATH-1 → · MATH-2 →
Energy Conservation (EC)
Only one year of past papers is available so far, so repeat patterns are still forming. See the current EC questions →
Applied Mechanics & Fundamentals of Electrical Engineering (FEE)
These are newer subjects on PSBTE’s syllabus — we don’t have enough past papers processed yet to show repeat patterns. Check back as more papers come in.
How we’re counting “repeated”
Every question is matched against every available past paper (as far back as 2011, depending on subject) and grouped by how many separate exams asked essentially the same question. The numbers above are real counts, not estimates.
FAQ
Does this apply to every stream (AE, ME, CE, EE)? Yes — 1st semester subjects are identical across every PSBTE diploma stream.
