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.

D.Coordinates body movements and auditory-visual processing

Jasmine is scaling up a bread recipe. The original calls for 4 2/3 cups of flour, but she needs 1 5/6 times that amount for a large family gathering. How many cups of flour will she use after scaling? Give your answer as a mixed number in lowest terms.

Correct

A.8 1/3
B.7 8/9
C.8 5/9
D.8 7/9

During a cycling event last weekend, I noticed several participants riding without helmets. With the sunny weather, it seemed some people prioritized comfort over safety. However, statistics from a cycling safety board report that cycling incidents cause many head injuries each year. Studies also suggest these injuries could be reduced by about 70% with the simple use of helmets. Despite the risks, only around 30% of cyclists routinely wear helmets, creating an unnecessary safety risk. Given these facts, helmet use is strongly recommended to reduce the chance of injury during falls or collisions. Based on the text, which statement would the writer most likely endorse about the benefit of wearing a helmet while cycling?

Incorrect

A.Helmets mainly protect against minor scrapes and have little effect on serious head injuries.
B.Helmets are only necessary for children or inexperienced cyclists.
C.Wearing a helmet can greatly reduce the chance of head injury in a crash.
D.Because crashes are uncommon, helmets are optional and do not meaningfully change injury outcomes.

D.Coordinates body movements and auditory-visual processing

The medulla contains autonomic control centers that regulate vital involuntary functions, including breathing and heart rate, making the choice mentioning “heart rate and respiratory functions” correct. The other choices better match functions more associated with the pons or midbrain (such as arousal/sleep regulation and auditory-visual reflex pathways) rather than the medulla’s core autonomic role.

Correct

A.8 1/3
B.7 8/9
C.8 5/9
D.8 7/9

Why 8 5/9 is correct To scale the recipe, multiply the two mixed numbers. Step 1: Change each mixed number to an improper fraction 4 2/3 = (4 × 3 + 2)/3 = 14/3 1 5/6 = (1 × 6 + 5)/6 = 11/6 Step 2: Multiply the fractions 14/3 × 11/6 = (14 × 11)/(3 × 6) = 154/18 Step 3: Reduce to lowest terms Both 154 and 18 divide by 2 → 154 ÷ 2 = 77, 18 ÷ 2 = 9 So 154/18 = 77/9 Step 4: Convert back to a mixed number 77 ÷ 9 = 8 remainder 5 → 8 5/9. Why the other answers are wrong 7 8/9 – comes from subtracting instead of multiplying the improper fractions. 8 7/9 – results from multiplying correctly but forgetting to simplify 154/18 to lowest terms. 8 1/3 – shows what happens if the denominator is copied incorrectly during the reduction step.

Incorrect

A.Helmets mainly protect against minor scrapes and have little effect on serious head injuries.
B.Helmets are only necessary for children or inexperienced cyclists.
C.Wearing a helmet can greatly reduce the chance of head injury in a crash.
D.Because crashes are uncommon, helmets are optional and do not meaningfully change injury outcomes.

The passage says studies show head injuries could be reduced by about 70% with helmet use and concludes that helmets are strongly recommended to reduce injuries during falls or collisions. This supports the choice stating that wearing a helmet can greatly reduce the chance of head injury in a crash. The choices claiming helmets have “little effect,” are “only necessary” for certain riders, or “do not meaningfully change” outcomes contradict the passage’s specific statistic and its recommendation.

What students say about Prepia for the HESI A2

“I used this app for almost 3 weeks to prepare for the Hesi A2. It was very helpful I wanted to just past and did 20- 30 questions 5-6 days a week. I'm a single parent with 2 toddlers so it is not easy to study. I was able to pass my Hesi today with a 77% score.”

L. Smith-Nomel· Google Play

HESI A2Passed with a 77%

“…This app brakes down the information in a way that’s easily understood, in turn giving me added confidence.”

“…I did not require the anatomy/physio for my hesi a2, however, with less than 24 hours to study I passed. Was worth it.”

Michelle WestHESI A2 · Passed

“Great prep. Passed with over 92% on everything. Two things it doesn't cover: 1) gallons/pints/cups to ounces, so be sure to brush up on your conversions! 2) Critical thinking! Find something to help you prep on this as well.”

Elise WheatonHESI A2 · Passed with over 92%

“I don't know if it's because of the app that I passed with an 80%. I passed it on my first try though! So I'll take, thank you!”
