About the Nail It Series

About the Nail It Series

Nail It is a series of ebooks containing questions on various topics in mathematics, compiled

from textbooks that are out-of-print. Each ebook contains at least fifty questions. The ideabehind the series is threefold:

(i) First, to give students sufficient practice on solving questions that are commonly asked

in examinations. Mathematics is not a spectator sport, and students need all the drill

they can get to achieve mastery. Nail It ebooks supplies the questions.

(ii) Second, to expose students to a wide variety of questions so that they can spot patterns

in their solution process. Students need to be acquainted with the different ways inwhich a questions can be posed.

(iii) Third, to build the confidence of students by arranging the questions such that the easy

ones come first followed by the difficult ones. Confidence comes with success in solving

problems. Confidence is important because it leads to a willingness to attempt more

questions.

Finally, to “nail” something is to get it absolutely right, i.e., to master it. Nail It ebooks to enable

motivated students to master the topics they have problems with.

If you have any comments or f eedback, I’d like to hear them. Please email them to me at

[email protected]. Finally, I’d like to wish you all the best for your learning journey.

Features of the Nail It Ebooks

Features of the Nail It Series Ebooks

1. The Nail It Series ebooks are completely free. The questions are compiled from textbooks

that are out-of-print and those that are very difficult to locate. As Winston Churchill oncesaid, “We make a living by what we get. We make a life by what we give.”

2. The Nail It Series ebooks have been designed with mastery of the subject matter in mind.

There are plenty of textbooks, and they all can help you get the “A” grade. Nail It ebooks

are designed to make you the Michael Phelps of specific topics.

3. Each Nail It Series ebook has a minimum of fifty questions, with each question appearing

on its own page. View it on your tablet or a mobile phone, and start working on them.

4. The Nail It Series ebooks are modular, and compatible with different syllabi used in

different parts of the world. I list down the links with the syllabi I am familiar with.

5. Students are usually engrossed in solving questions, and miss out on the connections

between different questions. Compare pages puts the spotlight on usually two, but

sometimes more questions, the solution of which are closely related. Contrast pages does

the same, but with two or more questions that look alike, but that require differentapproaches in its solution. Spot the Pattern pages challenge students to spot the pattern

underlying the solution process.

6. Essential to Know pages provides must-know facts about questions already completed. I

suggest committing the material presented in the Essential to Know pages to memory.

About Learning

About Learning

Many teachers today like to tell their students that learning is enjoyable, and that learning is

fun. What students quickly realise is that learning is often repetitive (and therefore boring),cognitively demanding (and therefore tiring), and time-consuming (and therefore costly). I’d

like to point out seven things that are needed for effective learning to take place. I suspect

teachers don’t mention them any longer because they are unpopular.

1. Learning takes hard work – a lot of hard work. But I’ve realised that all of life’s

worthwhile goals – setting up a business, starting a family, etc. can only be achieved with

hard work.

2. Learning takes dedication. There are no short cuts to learning. Learning is an intense

activity. Are you willing to learn at all cost?

3. Learning takes commitment . There are thing that you’ve going to have to give up, if you

want to learn. The price for mastering a subject matter is high. Are you willing to pay the

price (e.g., reducing the amount of time watching YouTube videos, or playing your

favourite computer game)?

4. Learning takes discipline. Closely tied to discipline is sacrifice, and a conscious effort to

minimise distractions. Are you willing to sacrifice (not meeting your friends so often,

watching less movies, etc.) in order to learn?

5. Learning takes motivation. And here, you have decide what exactly, motivates you. Are

you after an “A” grade, or are you after complete mastery of the subject matter? In other

words, are you happy with 75 marks, or would not be satisfied until you get 100 marks? A

gulf separates an “A” grade from complete mastery, and you have to decide what you are

after. This is because the game plan for each is different.

6. Learning takes participation. There are no “passengers” in learning. It is immersive, and

requires you to be interested, and alert.

7. Learning takes courage. It requires you ask people for help, step out of your comfort zone,

re-examine your assumptions, and make mistakes. All this takes courage, and requires

you to step out of your comfort zone. Are you courageous enough to learn?

About Dr Lee Chu Keong



58/58


Dr Lee has been teaching for the past 25 years. He has taught in

the Nanyang Technological University, Temasek Polytechnic, and

Singapore Polytechnic. The excellent feedback he obtained year afteryear is a testament to his effective teaching methods, the clarity with

which he explains difficult concepts, and his genuine concern for the

students. In 2015, Dr Lee won the Nanyang Teaching Award (School

Level) for dedication to his profession.

Dr Lee has a strange hobby – he collects mathematics textbooks.

He visits bookstores when he goes to a city he has never been to, to

find textbooks he does not already have. So far, he has textbooksfrom Singapore, China, Taiwan, Japan, England, the United States,

Malaysia, Indonesia, Thailand, Myanmar, France, the Czech Republic,

France and India. The number of textbooks in his collection grows

practically every week!

For mathematics, Dr Lee believes the only way to better grades is practice, more practice,

and yet more practice. While excellent textbooks are a plenty, compilations of questions are alot harder to find. For this reason, he started the Nail It Series, a series of ebooks containing

questions on various topics commonly tested in mathematic examinations around the world.

Carefully studying the questions and working their solutions out should improve the grades of

the students tremendously.
