Edition H2.2, equivalently edition 4.0 for the (Higher 2) H2 study guides, is our latest edition.
In response to feedback from readers, we intend to use "Edition H2.2" for all books associated with the revised H2 syllabus, regardless of their current numerical edition numbers.

Before edition H2.2, we have published 3 editions of our A-level study guides, each after a change in the associated syllabuses. Concurrently, we have also published other books - practice questions, practice MCQs, Higher 1 (H1) study guides, advanced study guides - each with their own numerically sequential edition numbers. Many readers have enquired about how the different edition numbers are associated. We therefore intend to use the same "Edition H2.2" for all books associated with the revised H2 syllabus, this being the 2nd major version of the Higher 2 syllabus. We believe it would better facilitate readers identifying the association among the books. We apologise for the confusion and misunderstanding caused.

Very approximately, the difference between edition H2.2 and the previous edition is about 20%.
For major differences, please refer to the content pages of edition H2.2 and 3.0 available at our Updates & Supplements page.
For details, please refer to the syllabuses available at SEAB's website.

Very approximately, about 80% of edition H2.2 and the previous edition are the same, i.e. about 80% of previous editions should still be relevant for exams from 2017.
For details, please refer to the current syllabuses available at SEAB's website.

Most of our books are written for the Singapore-Cambridge GCE A-Level (Higher 2) syllabuses.
Our "Advanced Study Guide Chemistry" is written for the Singapore-Cambridge GCE A-Level Higher 2 (H2) syllabus, with additional topics to cover the equivalent syllabuses of the University of Cambridge International Examination (CIE) A Level (Core & A2), and the International Baccalaureate (IB) Higher Level (Core & AHL).

Our books do not contain reproduction of the examiner reports - examiner reports are copyrighted material, and we were not aware of the copyright holders granting permission for their reproduction.

However, our authors do incorporate all applicable feedbacks from available reports into their notes and suggested solutions, or highlight them as common errors.

We are aware of publications that claimed to contain reproduced examiner reports - readers should want to verify that the reproduced reports are genuine by, e.g., comparing with available reports and/or enquiring with the subject teacher(s) who should have access to the reports.

Readers who are keen to read the original Examiner Reports and are attending a school/JC could try enquiring at their school/JC library - schoool/JC libraries should have these reports.

Cambridge International Examination (CIE) examiner reports, as well as syllabuses, past papers and mark schemes, are available for sale at CIE's website http://www.cie.org.uk/. While the CIE papers are slightly different from the Singapore-Cambridge papers, about 80% or more of the topics are the same. Readers should be able to have a good feel of what the examiners expect.

Readers may also be able to find other resources online with search phrases such as "singapore cambridge examiner report".

Our A-Level Study Guides (Higher 2) are written for the Singapore-Cambridge GCE A-Level (Higher 2) syllabuses.
Our "Advanced Study Guide Chemistry" is written for the Singapore-Cambridge GCE A-Level Higher 2 (H2) syllabus, with additional topics to cover the equivalent syllabuses of the University of Cambridge International Examination (CIE) A Level (Core & A2), and the International Baccalaureate (IB) Higher Level (Core & AHL).
We are exploring the viability of publishing similar Advanced Study Guides for other subjects.

The equivalent University of Cambridge International Examination (CIE) A Level (Core & A2) syllabuses are slightly different.
A large part of the syllabuses are however similar. The H2 level is approximately equivalent to the CIE A2 level. The CIE AS level is a subset of the CIE A level.

The H1 Chemistry and H1 Physics syllabuses are subsets of the H2 Chemistry and H2 Physics syllabuses respectively.
The respective H2 Chemistry and H2 Physics books are therefore useful for readers studying H1 Chemistry and H1 Physics too.
[ Note: The H1 Mathematics syllabus is however not a subset of the H2 Mathematics syllabus. ]

We seek our readers' understanding that, due to our limited resources and the low demand for H1 books, we have to discontinue publishing H1 books. [Our A-Level Study Guide Chemistry (Higher 1) was the only H1 book we were able to publish.]

All our books are up-to-date and in stock.
Any retailers claiming that our books are out of syllabus, outdated and/or out of stock is mis-informed.
We also provide updates which contain information that became available to us after a book was printed / re-printed.

Our books are distributed to many bookstores in Singapore. However, many of the bookstores are often out of stock.
If you can't find our books at a bookstore near you, please consider asking the store manager to (re-)order,
or see our Order Page for more information / options.

Our books are currently distributed only in Singapore.
However, readers outside Singapore can order our books by mail (from BL Toh Enterprise), or
consider digital versions of our books available as ebooks on Google Play.

All our books are now also available as ebooks on Google Play.
We are currently exploring the viability of other electronic / digital media.

According to Google Play, ebooks could be read offline / with no internet connection if readers download the ebooks to their device via the "Make availabe offline" option or the equivalent. Once the book has finished downloading to readers' device, it could be read anywhere even when there is no internet connection.

We seek your understanding that due to our limited resources, we are currently unable to provide print-able ebooks, i.e. all our ebooks are currently read only.

The 'Table of Contents' of Google Play Books are added by The Google Books Team, according to their page numbering system. The discrepancies have been brought to their attention, but they have indicated that they "are not planning to make them correspondent" due to various considerations. The links from the 'Table of Contents' are however correct.
We seek your understanding that this feature is beyond our control. For the correct page numbers, we recommend referring to the "Contents" page and, where available, the "Index" pages

We seek your understanding that due to our limited resources, we are currently unable to provide pdf versions of our (e)books.

You should be able to bring the defective book(s) back to the retailer for an exchange - this is the usual retail practice.
Please let us know the name of the retailer if you are unable to exchange the defective book(s) and we will arrange for the distributor to look into it.
We seek your understanding that defects could occur during the printing process and while our printer has a quality control process, it is practically impossible to detect all defects.

For Mathematics, the equivalent of our "A-Level Practice Questions - Chemistry / Physics"
was our "A Level Challenging Questions - Mathematics".
For our "H2.2" editions, it would be published as "A-Level Practice Questions" too.

All our A-Level Practice / Challenging Questions / MCQ books contain suggested solutions that show the essential steps taken to apply the relevant theories. Relevant feedbacks from Examiner Reports are incorporated into the solutions where possible, or appended as notes (NB) where appropriate.

The dots in front of some of the suggested solutions are bullets for those sub-paragraphs that do not have a paragraph number associated them.

The numbers in square brackets [ ] at the end of a (part) question are the number of marks given to that (part) question.
The format is similar to that in the actual exam papers. By using a similar format for our questions, we hope readers will become more accustomed to the actual exam question format.

Our "A-Level Practice Questions Chemistry (Higher 2) Ed 1.0" (ISBN 978-981-05-6523-7) was inadvertently reprinted in 2011 with an old back cover showing an incorrect price of S$21.95 (incl. GST) (for 5% GST).
The list price of this book remains at: "S$20.90 (without GST)" and "S$22.36 (with 7% GST)".
We apologise for the misunderstanding caused.

We regret to report that we currently do not publish any books on Biology.

We seek our readers' understanding that, due to our limited resources, we have to discontinue our online suggested solutions.
