PE Mechanical exam at a glance
PE Mechanical section breakdown
The PE Mechanical mock test on Wrexa Edge replicates the real exam's section structure — same names, same question count per section, same time limits. No inter-section breaks — the timer runs continuously.
PE Mechanical scoring & marking scheme
100–1000
Scaled score range
Strategy: PE Mechanical has no negative marking. Attempt every question — blank answers cost you potential marks but cannot pull your score down.
Scale: PE Mech (pass ~50/80).
How PE Mechanical is conducted
Mode
Proctored — Wrexa Edge mirrors this with a webcam-based proctoring flow (face detection, room scan, fullscreen lock, tab-switch detection).
Test format
Linear / fixed-form — every candidate sees the same number of questions per section.
Backtracking
Allowed — you can revisit and change answers within a section.
Mark for review
Available — flag tough questions and return to them before submitting the section.
Tools available during the PE Mechanical exam
Wrexa Edge renders these tools inside the mock test exactly as they appear on the real PE Mechanical exam — same shortcuts, same behaviour.
PE Mechanical time strategy
With 80 questions in 540 minutes, you have about 405 seconds per question on average. Successful candidates aim for the following pacing on each section:
Wrexa Edge's analytics show your actual time-per-question after every mock so you can spot which sections you're losing time on.

PE Mechanical (80 Q) · Math — Series
Q1. NUMERICAL: The Taylor series of e^x about x=0 is:
Why: Correct answer: D — 1 + x + x²/2! + x³/3! + … = Σ x^n / n!. Topic: Math — Series.
PE Mechanical (80 Q) · Prob — Basics
Q2. NUMERICAL: A fair die is rolled. The probability of rolling a 4 OR a 6 is:
Why: Correct answer: A — 1/3 — P(4) + P(6) = 1/6 + 1/6. Topic: Prob — Basics.
PE Mechanical (80 Q) · Prob — Independence
Q3. NUMERICAL: Two events A and B are independent with P(A)=0.3 and P(B)=0.4. P(A ∩ B) =
Why: Correct answer: B — 0.12 — independence ⇒ P(A)·P(B). Topic: Prob — Independence.
PE Mechanical (80 Q) · Stats — Mean
Q4. NUMERICAL: Mean of the dataset {2, 4, 4, 4, 5, 5, 7, 9}:
Why: Correct answer: C — 5 — (2+4+4+4+5+5+7+9)/8 = 40/8. Topic: Stats — Mean.
PE Mechanical (80 Q) · Stats — SD
Q5. NUMERICAL: Sample standard deviation s of {2, 4, 4, 4, 5, 5, 7, 9} (n=8, x̄=5):
Why: Correct answer: D — ≈2.14 — Σ(x−x̄)²/(n−1) = 32/7 ≈ 4.57; √4.57 ≈ 2.14. Topic: Stats — SD.
PE Mechanical (80 Q) · Stats — Normal
Q6. In a normal distribution, approximately what percentage of the data falls within ±1σ of the mean?
Why: Correct answer: A — 68% (68.27% exactly). Topic: Stats — Normal.
