A:
How much does delivery cost?

Q:
A:
What software was used to design the books?
The books were written in Microsoft Word 2007, and the graphs were drawn with the free software "Graph" (download link available from the useful links page).
While Word is usually disfavoured for mathematical publications, recent improvements in the Equation Editor tools have seen it become easier and faster to use and much more stable. Using Word has the advantage that equations can be visually inspected before the document is finalised (unlike in LaTeX).

Q:
A:
Can I see a sample of the books?
Certainly; a sample containing selected items from the Teacher's Notes and Worked Answers books is available for download.

Q:
A:

Should I be teaching everything in the books?
As with everything, it depends on the calibre of your students. The books are structured in such a way that they contain material accessible and relevant to students at all levels of the Scholarship Calculus standard: there is a lot in them. If your students' goal is to attain Scholarship (rather than Outstanding Scholarship), then some of the material may be too much for them. In this case, your time would be better spent using the less advanced parts of the books to emphasise conceptual thinking, problem solving and communication skills, rather than trying to extend students further laterally. If you would like advice on areas of the course which I find most beneficial for my students in that situation, see my recommendation on the downloads page. For further advice, please contact me.

Q:

A:
I am a student / parent of a student who is undertaking Scholarship preparation individually. 
Can I purchase your books?
Absolutely - please order as usual.
If you are just working individually, I would recommend purchasing the Teacher's Notes and Worked Answers.

Q:
A:
I have found an error!
Please let me know immediately; I will fix the error for future print runs and upload a notification of the change.

Q:
A:
Can you please clarify ... or offer further examples?
Please contact me with you query and I will do my best to address it as soon as possible.
Please don't hesitate to ask if you feel something is inadequately explained or illustrated, as I can then improve those areas for future print runs and let others know.

Q:
A:
Have you ever considered adding ... to the books?
Please let me know any suggestions you may have - if possible, I will attempt to include the suggested material in future print runs and will distribute the update to those who already have a copy of the books.

Q:
A:
What is the logo?
The logo shows a 3D spiral shape which is the combination of many different 2D golden spirals, lifted up to different amounts (the ends of two such spirals can be seen as the black lines on the outside of the surface).
Golden spirals are logarithmic spirals which get wider by a factor of φ (the golden ratio) every quarter turn.

Q:
A:
What does the name 4tφ mean?
4tφ has no mathematical meaning, but is a play on words (or symbols) which reads "four-tee-phi", or "fortify".
This name was chosen because, if the Scholarship Calculus exam is seen as a war between students and the examiner, then this package is a way of building students' defences against the deadly weapons of confusion and "I don't know".
