How is this different from a prep book?

A book shows you questions; Prepia learns from your answers. Every session is scored instantly, your progress is tracked by subject area, and missed questions become your next study session. The same bank follows you across phone and web, so practice fits wherever your day happens.

How long do I need to prepare?

Most students study four to eight weeks, but the honest answer depends on your baseline. Start with a practice session, look at your category scores, and put your time where the gaps are. Short, consistent sessions beat cramming: the app is built for exactly that.

Can I study on my phone?

Yes: Prepia runs on iPhone, Android, and any browser with one account and synced progress. Answer ten questions in line for coffee, review rationales on the couch, and take a full practice run at your desk.

What happens if I don't pass?

Our Pass Guarantee kicks in. If you do not pass your exam, we refund your purchase in full. We do not ask for a score report. The full terms are at prepia.com/docs/pass-guarantee.

Incorrect

A.8 days
B.2 days
C.6 days
D.12 days

Why "6 days" is correct Marco takes 5 days for one bridge. For three bridges: 5 days × 3 bridges = 15 days. Nina takes 3 days for one bridge. For three bridges: 3 days × 3 bridges = 9 days. The difference is 15 days − 9 days = 6 days. Why the other answers are wrong 2 days: This would be the gap if the rates were closer, but the real gap is larger. 12 days: Someone might mistakenly subtract 3 from 15 and then double it, but that is not the right method. 8 days: This could come from mixing the numbers 5 and 3 incorrectly (for example, 5 + 3 = 8), but it does not represent the time difference.

Correct

A.Dampers (shock absorbers)
B.Tie rod ends
C.Sway bars
D.Alternator belt

Dampers (shock absorbers) control spring motion and dissipate energy so the vehicle stops oscillating quickly after a bump. If dampers are worn or leaking, the springs are underdamped and the car will continue to bounce several times. Tie rod ends primarily connect the steering system to the wheels and affect steering looseness and alignment rather than vertical bouncing. Sway bars mainly reduce body roll during cornering, not repeated up-and-down oscillation after a single bump. An alternator belt is part of the engine accessory drive system and is unrelated to suspension motion.
