For revision I found a proper plan helped. But make it realistic and start as early as possible so if you miss days you don’t end up in a flap.
Find out when you work best. I can work solidly from 8am to about 1pm. After lunch it’s less productive. After 4pm and it’s just isn’t worth bothering (so I didn’t and planned this in). Somepeople do mornings some do late nights…
Find a style that works. I used to condense my notes. BAsically rewriting them until I could get an entire course onto a side of A4 with the key words/phrases triguring memories.
Have proper breaks. If you find your mind wandering then get up, be distracted but give yourself 5 or ten minutes then get back to work. Working in a half hearted way is not effective. Better ot stop and and then restart.
Coffee.
Get “the fear”. I found at uni doing a couple of past papers after reading through my notes once scared me as I couldn’t do them. Fear was a great motivator.
Have a goal. Why are you revising and what reward will it bring.
