About the store
I have over 20 years of experience teaching in Secondary (High) School in Australia. I major in Chemistry and all levels of Mathematics. I have been coding Excel Spreadsheets in VBA / Macros for over 6 years and have done several for various colleagues and even for whole school use - all with VBA coding stored in the file.
I have seen so many spreadsheets where colleagues (without a high level of IT confidence) have accidentally deleted the important information that makes the spreadsheet work - hence why I moved to programming them from behind.

Teaching style
I am a firm believer in learning for mastery and that means practicing skills and memorizing information so that it can be recalled when needed in exams. The resources that I create for myself and others focuses on students practicing C-level questions until they repeatedly get them correct from the time that I teach the concept to them in class and then each week until the assessment.
