1. Is is a combination of important thing of science.A very good app but questions are repeated in next level and we have to go through all the bookmarks if we want to see the last one.Showing incomplete questions which are long.Resolve this problem.Also plz add an option to report about the wrong answers if any given by the app.
2. Answers of some ques r exactly wrong....correct them E.g nucleon do not contains ---answer is given in the app is positron...bt electron is also given in the options which is also trueGood question collection.
3. e.g ques--supersonic jet airplanes causes the pollution by the thinning of ------?answer should be ozone layer but oxygen layer is given in the answer.Guide abt this.
4. E.g. the colours of light are related to the frequency (or wavelength), but definitely not the amplitude, which was given as the correct answer.
5. So please keep this.Very useful app...I get to know about the things which are new for me...and it has a very good feature that until you get all the questions correct you can't go to the next level.
6. I like and prefer it because in each and every level, when you couldn't able to give all answers correctly, variety of questions would remain in every time.
7. when u click on a right answer it'll show u wrong.
8. Then in the Solution Page it'll show u the right answr which previously showed u wrong.
9. Please concentrate on correct answer marking.
10. Needs lots of ImprovementThat is a very good and helpful for every student mainly arts background student.
11. A few of the answers are just plane wrong.
