                                                     Organizing Yourself

     Many new students find it hard to do all the study that has to be done；they find themselves putting

off reading assignment, jumping from one subject to another and rarely being quite certain what they are

trying to do during a particular study session.The best way to overcome these difficulties and to start

studying efficiently is to plan your time and organize your work.Let us suppose that you have 15 hours

per week of classes and that you decide to allow yourself a 40hour working week (a reasonable figure,

leaving you 70 waking hours for other activities).

     You now have to decide how to divide the remaining 25 hours of private study.Naturally the decisions you make will change from week to week according to what essays have to be written and what reading

has to be done.Many people find it helpful to draw up each week a sevenday timetable showing the

occasions on which they will be working privately and the particular subjects that will be studying on

each occasion.By checking such a plan at times during the week, you can see what you have done and

what you have still to do:the whole plan becomes more manageable.There are a number of places where

you can study college library, public library, home, empty classrooms, on bus or train and each has

several obvious advantages and disadvantages.The college library is least busy in the evening, on

Wednesday afternoon, and all day Friday and Saturday.

     When you are deciding where to study, keep the following suggestions in mind:

1. Try to study always in the same place.After a while the familiar surroundings will help you to switch 

     into the right frame of mind as soon as you sit down.

2. Find somewhere with as few distractions as possible.

3. Make sure that your study place has a good light and is warm (but not hot) and well aired.
