Work through the manual from the beginning. You know that it is divided into 3 sections. It is a good idea to complete a whole section in one go if you can. At the beginning of the section you will find a list of skills you will learn. Read these carefully and return to them when you have completed your work. It is important that you do not move on until you have learned all the required skills. Read each section carefully. You may come across new words which you do not know. These should be explained in the glossary at the end of the manual. You will.
