CIE Chemistry Quiz

This app, with 200 questions, is aimed at A Level students of chemistry following the 2016-2018 version of the Cambridge International Examinations (CIE) syllabus (9701). The tests are loaded by clicking on the name on the Mobile device, i.e. PHYSICAL, ORGANIC and INORGANIC and PRACTICALS as well as A2 material (i.e. physical, organic and inorganic) for more advanced A Level students according to the syllabus.After launching the app on Mobile and choosing your quiz, you will see a notification on Wear. Open the notification on Wear and you are presented with the first question. Sliding your finger to the left gives the first out of four similar views in which to choose (press the Wear screen firmly or double tap); only one correct answer is required. Sliding to the right gives the option to ignore the question and go to the next. The question/status is always seen on the Mobile device but not the answer. Green indicates a correct answer, red for incorrect and yellow for ignored. Clicking the New Quiz at the bottom of Mobile gives you the ability to start a new quiz of your choice with the usual notifications. When the quiz ends (or user terminates the app) the score is viewed on Wear.

The screen is kept awake on the main screen for uninterrupted quiz use and there is also RTL input.

In the event that a connection is lost between Wear and Mobile, simply relaunch the app again on Mobile once reconnected. You can create your own questions and answers on-the-fly on Mobile to test your friends on Wear (with individual quiz status notification), which you can reset with the Reset button on Mobile.

Much of the theoretical part of the syllabus is covered, but some obvious limitations due to small screen size.

A REFERENCE GUIDE is included via the menu bar. It covers many of the topics included in the quizzes and includes calculators and aides for some of the scientific theories. You can save output to your device in one example as it is commonly required in practicals (see image).

A UI has been included on Wear so you can launch the quizzes directly from Wear; the app already must be on the main screen activity on mobile.

You can install and use the app without Wear, but of limited use. Android Lollipop or newer represents the best viewing of the chemical formulae.

A small font size is recommended for Wear..

Topics covered that you need to know:

GENERAL/PHYSICAL CHEMISTRY: relative atomic masses, mol/molarity, electronic structure of the atom, bonding, VSEPR, solution chemistry, titrations, weak/strong acids and alkalis, ideal gases, chemical thermodynamics, chemical equilibria, electrochemistry, reaction kinetics including catalysis.

ORGANIC CHEMISTRY: stereoisomerism, hybridisation, trends, alkanes, alkenes, alcohols, carbonyl compounds, acids and their derivatives, halogenoalkanes, organonitrogen compounds including amino acids and proteins. Arene chemistry and electrophilic substitution as well as the special chemistry of phenol. Brief overview of organic synthesis and medicinal chemistry. Arenes, polymers and amine derivatives are usually taught in the second year (A2), but also introductory polymers in A/S. Mechanisms are included in the reference guides.

INORGANIC CHEMISTRY: periodicity, Groups 1 and 2, aluminium, nitrogen, sulphur and Group 17 (halogens). Transition metals and their coloured compounds, co-ordination compounds.

Also some chemical analysis and spectroscopy.
