English Tests AIO (All-In-One) Customer Insights

1. The text is terrible small and sometimes is very difficult to read and should be easier the options are on vertical and not on the horizontal.Great! But some answer options are hidden when not using full screen,, hope you would improve that,, Thanks a lot anywayI installed it on the basis of its rate and reviews....it's a good app to learn...but i think there are some errors in their answers...the main issue is that it always get stuck on the same question...having completed the level test then continuing with grammar n vocabulary test not able to go for the next question it always stops after the 4th question...everytime I restart the app the same thing is happening....HIGHLY DISAPPOINTEDAll in one app.

2. I would like to suggest adding IQ tests included,it would be extremely helpful,however, the app and website both are very easy to use and very helpfulIt's a good tool to prepare for the tests and the app works fine.

3. From the little I managed to see it looks like it might have a potential but it's just too glitchy.The grammer and sentence structure is weird and doesnt sound "normal", I would use this to prepare for a b1, b2 and certainly not C1 and C2 tests.

4. Also, some questions have answers where they all make sense (C1, I ___ remember placing it on the shelf) Grammar and vocab us decent however.It is a very interesting app.

5. At first I only wanted to give it four stars but then I dicided to rate it five stars.Doesn't work, didn't load, crashed.

6. Keep up the good work!Everything is really amazing except that the answer in the box is cut somethimes when it is too longNot the best.

7. But sometimes there are some mistakes in my opinion.I mean, errors in the answers and questions.

8. Using this app I get pleasure that I can remember the rules of the English language.

9. Great for advanced english learners like me.

10. The proficiency tests honestly don't give a lot of context to the situation.

11. A1 maybe, very very very basic english in this test.
