Download here parts of Mastering Physics and of ProblemSolving.
Included are the content pages, introduction and the starts of the AS and the A2 sections of Mastering Physics, and all of Developing ProblemSolving book.
Developing ProblemSolving Skills gives fully worked solutions for two
isaacphysics problems to illustrate the methods and skills being developed.
It also gives a sample question from each section of the isaacphysics
MOOC.

parts of Mastering Essential GCSE Physics.
Included are the content pages, introduction, notes for teachers, and how to
use the book. Then follow the first 13 sections of the book, covering
basic skills and most of mechanics.
For teachers: on the book pages you will find:
A specification map linking your board's topics with the appropriate book
section. One more click will set as homework the section being taught! See
the teacher notes about marking and analysis of results by Isaac.
A hyperlinked pdf of the book text plus examples for class room projection
is available on the book's web pages.

parts of PreUniversity Mathematics for Sciences. Included are the content pages, introduction, and the first two chapters, that is the most elementary levels 1 and 2 from Isaac (end of GCSE and start of Alevel).
The first reprint has been expanded (October, 2018) from 96pp to 160pp. Graph sketching has been added to each of chapters 16, and is hugely important for understanding scientific results at a deep level, and is much sought after in students by top universities. Chapter 7 has been expanded to 9 sections to cover an eclectic range of topics  vectors, exponentials, formulating problems, population dynamics, parametric functions (including the log horns of the book's cover), yachting, rainbows, an integration challenge.

parts of A Cavendish Quantum Mechanics Primer.
This primer takes able readers from their penultimate school year to well into the second year quantum mechanics course in physics at Cambridge. It is not a textbook, but a primer introducing essential ideas, analytical skills and the solving of problems  much in the style of the Cambridge physics course.
The Primer is challenging, but within the reach of a committed Alevel student.See here for how it is used by Alevel students, and how it can help you gain insight into Quantum Mechanics, and gain fluency and confidence in maths and physics.
