Official GMAT | Manhattan Prep for Android

The math answers provide minimal explanations for the solutions. Maybe this is good for someone with already great math knowledge, but I need to know how/what rules were used to solve. At the very LEAST, what category of math it’s called so I can google it myself.

Very first quiz and there is no consistency in the math problems. For instance some questions consider prime factors to include 1 and n, some do not, some count multiple same factors, some do not, but absolutely no rhyme or reason. It’s clear from community scores on those questions you have a problem.

Like very very basic bugs (like screen rotation) with the pop up text showing up cut off in the wrong orientation (portrait vs landscape). Half the time the pop up questions show up off-screen, and I’ve only been using this app for 2 minutes. come on manhattan prep...

Downloaded this app on my Android XS and the app won’t even open. Crashes instantly.

What a rubbish app. I paid for yearly subscription by creating and registering with an account. I am not able to login neither I am able to get a response from the management after sending 2 emails back to back for a refund. PATHETIC SERVICE FROM MANHATTAN GMAT !!’
