 been issued to supplement NavPers 10052 for your

 are listed by rate level in NavPers 10052. If 

 you are worlcing for advancement to third class,

 some Navy Training Courses are marked with an 

 asterisk (*). Any course marked In this way Is 

 MANDATORY — that is, it must be completed at the 

 indicated rate level before you can be eligible to 

 take the servicewide examination for advancement 

 in rating. Each mandatory course may be com- 

 pleted by (1) passing the appropriate enlisted 

 correspondence course that is based on the manda- 

 tory training course; (2) passing locally prepared 

 tests based on the information given in the train- 

 ing course; or (3) in some cases, successfully 

 completing an appropriate Class A course.

 standards for advancement. Personnel of ALL 

 ratings must complete the mandatory military 

 requirements training course for the appropriate 

 rate level before they can be eligible to advance 

 in rating. 



The references in NavPers 10052 which are 

 recommended but not mandatory should also 

 be studied carefully. ALL references listed in 

 NavPers 10052 may be used as source material 

 for the written examinations, at the appropriate 

 rate levels. 



Navy Training Courses 



There are two general types of Navy Train- 

 ing Courses. RATING COURSES (such as this 

 one) are prepared for most enlisted ratings. 

 A rating training course gives information that 

 is directly related to the occupational qualifi- 

 cations of ONE rating. SUBJECT MATTER 

 COURSES or BASIC COURSES give information 

 that applies to more than one rating. 



Navy Training Courses are revised from time 

 to time to keep them up to date technically. 

 The revision of a Navy Training Course is 

 identified by a letter following the NavPers 

 nimiber. You can tell whether any particular 

 copy of a Navy Training Course is the latest 



edition by checking the NavPers number and 

 the letter following this niunber in the most 

 recent edition of List of Training Manuals and 

 Correspondence Courses, NavPers 10061. (Nav- 

 Pers 10061 is actually a catalog that lists all 

 current training courses and correspondence 

 courses; you will find this catalog useful in 

 planning your study program.) 



Navy Training Courses are designed to help 

 you prepare for advancement in rating. The 

 following suggestions may help you to make the 

 best use of this course and other Navy training 

 publications when you are preparing for advance- 

 ment in rating. 



1. Study the military qualifications and the 

 occupational qualifications for your rating before 

 you study the training course. Remember, you 

 are studying the training course primarily in 

 order to meet these quals. 



2. Set up a regular study plan. It will prob- 

 ably be easier for you to stick to a schedule if 

 you can plan to study at the same time each 

 day. If possible, schedule your studying for a 

 time of day when you will not have too many 

 interruptions or distractions. 



3. Before you begin to study any part of 

 the training course intensively, become familiar 

 with the entire book. Read the preface and the 

 table of contents. Check through the index. Look 

 at the appendixes. Thumb through the book without 

 any particular plan, looldng at the illustrations 

 and reading bits here and there as you see things 

 that interest you. 



4. Look at the training course in more detail, 

 to see how it is organized. Look at the table of 

 contents again. Then, chapter by chapter, read 

 the introduction, the headings, and the subhead- 

 ings. This method will give you a pretty clear 

 picture of the scope and content of the book. As 

 you look through the book in this way, ask your- 

 self some questions: 



What do I need to learn about this? 



What do I already know about this? 



How is this information related to information 

 given in other chapters? 



How is this information related to the quali- 

 fications for advancement in rating? 



5. When you have a general idea of what is in 

 the training course and how it is organized, fill 

 in the details by intensive study. In each study 

 period, try to cover a complete unit — it may be 

 a chapter, a section of a chapter, or a &ubsection. 

 The amount of material that you can cover at one 

 time will vary. If you know the subject well, or 

 if the material is easy, you can cover quite a
