Ace for Engineering & the FE and PE

Show the units. Then shut it down for the night. Ace grills you out loud on your classes and explains every miss.

New Ace accounts start with free credits · School asks use Ace credits at 2× the Ace rate · Ace never records your voice

Grill me

Ace asks. You answer out loud. Miss one and Ace explains it.

Pick a class and tap the chip. Ace reads each question in its own voice, listens to your answer, grades it like a senior engineer would, and saves every miss to a review deck.

Ace asksFor a first order linear differential equation, why does multiplying by an integrating factor help you solve it?

YouI'm not sure.

Here's the answer.The integrating factor turns the entire left side into the derivative of a product, so you can integrate both sides. This uses the product rule and the first order linear differential equation method in the NCEES Reference Handbook. Remember: make a product derivative, then integrate.

What's inside

Everything for the hard years.

FE and PE-style questions

Problems with units, A–D, with every step shown. They arrive one at a time: start on the first while Ace writes the rest.

Study guides and flashcards

Name a topic or paste your notes. Ace writes the guide and deals a deck that comes back on a spaced schedule: again, a day, three days, a week, three weeks.

Calm, built on our sound research

Focus sound from our FocusFrequency research, nature and noise, and guided meditations in Ace's voice. Every sound shows its evidence grade.

A study clock that protects your sleep

Work in blocks with real breaks. Check in with your sleep and stress, and Ace plans the day around it. After bedtime it won't start a new block.
