Revising; how to get more bang for your buck

We all want to get the maximum out in return for whatever we put in. It's natural. We want value for money or "more bang" for our buck. We want more result for the time we expend.

Let us consider what research reveals about different methods for revision....

We remember on average:

10% of what we read. This is why I can read the newspaper in the morning and have forgotten almost everything by the time I get home from work.

20% of what we hear. This is why I don't remember any of the lyrics of songs I hear on the radio.

30% of what we see. This is why I can walk past a picture on my wall at home and occasionally notice something I've never seen before. 

50% of what we see and hear at the same time. This is why I have only a vague memory of what happened in the last season of House of Cards.

70% of what we say. This is why I'm better at remembering that really useful explanation of security for costs I gave last week.

90% of what we say and do at the same time. This is why I remember the diagrams I draw on the white board in a class whilst talking through a point.

What does this mean?

Think about it this way - you can read for an hour and only get a return of 6 minutes' worth of retained material. It means that you can spend three days reading Professor Stuart Sime's A Practical Approach to Civil Procedure and only retain the equivalent of 5 of its 50 chapters. 

And in all probability you will only retain small smatterings of information scattered across the whole book.

That can't be good enough, can it? For three whole days work?! 

So what would be better? 

Well, some students think that if they read whilst highlighting the "important" parts of the text, that they will remember. Often, this is done on the first full reading of the topic in question. 

This doesn't work very well... because the student doesn't yet have a proper understanding of the subject matter to sift it. 

As a result.... it all seems important. 

"But I thought it was ALL important!"

Highlighting seems like an "active" thing to do. But what processing of the information is going on here? I think at best you are giving your hand something to do. It isn't active learning. 

A combination of annotation in several colours and highlighting would be better. 

Can this be improved upon?

Yes. There are many methods that you can use, all of which mean an outlay of more time initially, but pay off with better retention of the information handled. 

Old fashioned note taking

Going through a combination of your own class and lecture notes, the tutor's handout, class slides, the text book and the practitioner's text to pick out the essential points which are noted down. 

Use of colour is recommended; using both the left brain and the right brain boosts memory retention.

This is time consuming, but if done well, you can put away all of your other resources and proceed using your notes alone; a single effective source for future learning. 

Record cards

Small format record cards are an ideal place to have key points jotted down. Portable and handy, they allow you to revise in stolen moments; on the train, between tasks, waiting for friends. 

The discipline is in working out what the key points to put on the cards are - mentally sifting the important from the irrelevant detail.

Again, the use of colour is recommended.

I made record cards for GCSE, A Level and for case revision on my LLB. My mum probably still has the little boxes of the cards in the loft of my childhood home. 

Flash cards 

The easiest way to test yourself. Quick, cheap and easy to make. You can test yourself or get others (even those who know nothing of the subject you are studying) to test you. 

It's a great way to get others involved, which will make the whole task of testing yourself a little more fun.

Recording your own podcasts 

I don't mean just read the textbook into your phone. I suggest organising your notes first - so that you have some structure and understanding of topics before you begin, and then carefully narrate and record sound files for listening to on your phone, iPod or tablet.

Audacity is a free application which will allow you to record sound files, although many phones have similar free apps which achieve the same aim. Once done, re-listen when jogging or travelling. A way of enjoying a walk or run, without feeling guilty about being away from your desk.

Mind maps

Developed by memory genius Tony Buzan, these are diagrams that work in the same way as your brain does; by making connections. 

You begin with a central theme, with arms radiating out of the centre. The items which are only 1 line removed from the middle are the key concepts and headline points; as you then radiate outwards, you can see the relationship from the central theme. You need an understanding of the topic before you make a mind map, and there may be other details you will need to learn by means of another technique, but this is a good way of organising your knowledge.

Teaching each other in a study group

If you remember 90% of what you say and do at the same time, it should be clear why teaching your friends a given subject is highly likely to fix it in your mind. Spread the misery! Get your fellow students to share out syllabus topics and take it in turns to teach and learn. Particularly where there is a very large syllabus, this can be a brilliant way to achieve coverage. 

What do all of these methods have in common - they are all methods of active learning. Active learning is always better than passive learning. Listening and reading are classic methods of passive learning, and as you can see from the statistics I've set out above, the levels of memory retention for passive learning are poor. Your time will be far more efficiently spent using methods which are active. 

Please don't convince yourself that you "don't have time" to make notes, flashcards, mind maps, form a study group or record your own podcasts. Time efficiently spent will end up time well spent. 

Give it a try!
