Community Voice & Feedback
The way the app was allowed for me to see the whole bank and retest as necessary the new bank is 3x as long and doesn’t allow me to view all questions once …. The update is counter productive.
Now there’s more questions that not appear in the real test
I think y’all should ho back to the original way it looked with CORE having only 224 questions there to many questions in the way or make a mode for only the 224 plz and thank you
Some of the questions are outdated. The use of CFC R-13 and R-503 are no longer used . So if this type of question is in the exam this will confuse anyone.
Questions were almost identical to the actual, aside from the app being a little outdated in terms of design and functionality. It is great and worth the $10
If you want to pass the test review this passed it first time
I have been trying to study for this test and everytime I move my phone ends up rotating the screen causing the entire app to stop working and be in disarray allowing me to never finish a full test knowing what I missed
Failed my epa 608 universal 2 times, I decided to buy this app to help me study. This app pretty much has most of the questions on the test. Just passed with a 70% just now! This app saved me
Helped study for the test, a lot of the questions on the study tests, thank you!
I should start off the review by saying that the app is good in respects to what you can expect to see on the actual exam and should be used more as a supplement to actual studying (which I recommend skillcat), but I did note a few things that felt careless by the developers. For starters, I saw it had older and outdated questions that aren’t in modern versions of the section 608 exam. I’m not sure how the questions are gathered but they should be up to date with modern versions and exclude content from outdated versions of the exam this app is for. This aspect really fluffs the use of this app and provides unnecessary information and questions that gets in the way of studying for a modern version of the section 608 exams. Another thing I took note of was the app experience falling short in optimization, I was surprised to see there wasn’t an option to go back to previous questions on the practice tests. All in all, I did find this app useful to test my knowledge in preparation for the section 608 exams but felt held back by all the outdated content.
🙏🙏🙏🙏
The practice test they provide on the testing website has maybe 30% of the questions this app has 100% of the questions on the test I can’t push this out there enough get this app it’s so worth it
Used this app alone to study for the exam and passed with 90+% on all sections.
I GOT UNIVERSAL FROM THIS APP, MAJORITY OF THE QUESTIONS ARE ON THE TEST. 10/10 MUCH APPRECIATED.
Be prepared to not be able to go the next question or get to the last question then the app will crash leaving you not knowing what you got wrong and what you got right. Tilting the phone causes the app to freeze as well
