📝 About this app
Created by an experienced Chemistry Teacher and designed around the AP Chemistry course - amended for updated CED being introduced Fall 2024.
For obvious copyright reasons, none of the questions can come directly from AP Chemistry exams. However, questions have have been chosen to be the appropriate level and wording has been changed to reflect the style of the AP Exam.
Questions would be appropriate for the Physical & Inorganic Topics found in most courses that are aimed at top of High School/early University level.
Includes comprehensive Notes for all 9 Units, almost 1000 MC questions and a set of Cards with hints, advice and questions not suited to MC format.
Cards can be viewed in their default order or randomly mixed.
To maximise efficient use of time, Cards that are well understood can be sent to the bottom. Cards that need to be attempted again, can be sent to the top. This order can then be saved.
Loading the saved set of Cards ensures that Cards are in the best order to maximise your study.
Quiz questions can be randomly loaded in multiples from 10 to 60 questions at a time. From single Units or from multiple Units.
There is the option to select from a bank of over 400 MCQ that are specifically Exam Practice.
There is a collated set of 60 MCQ that attempt to replicate the range and balance found in a typical AP Chemistry Exam.
Hints & Explanations have been added for all 9 Units.
Questions answered wrongly are added to a Review pile.
A simple tally of percentage of questions answered correctly helps monitor progress within each individual Unit. These can be archived, allowing progress to be reset to zero whenever you wish a 'fresh start'.
Data sheets including a Periodic tables and Formulae/Equations can be accessed at any time from within the quiz.
Cards will increase. MC questions will be constantly amended/improved and additional questions will be added regularly.
