One of the most important things is your environment - you need to have everything you need before you begin so that you're not leaving your desk every five minutes for that glass of water or that snack. For me, I need to have some water nearby, a healthy snack (or two in this case!), paper, pens and loads of post-it notes.
Studying in your prom dress won't make you very productive at all so I always make sure I'm wearing something comfortable. Mostly, I'm either in pyjamas (yes, really! Even though it can make answering the door quite awkward!) or a jumper and sweats/leggings. I find that my study pose is sitting cross-legged so whatever I'm wearing has to allow for copious stretching!
Paper, paper and paper. And pens, pens and pens!
I go through so much paper and so many pens when it comes to studying. Technology doesn't have a look in as I prefer to write everything down by hand even though it does often take longer than if I typed it all.
I mentioned these last time but this is my favourite technique for revision - write everything down on one side of A4 and stick with just that one side. This encourages you to write down only the necessities and helps you break the stuff down into a manageable amount. Basically, if it's not worth knowing, it won't be on that sheet of paper; at least, that's the principle behind why I do this.
This cute to-do list pad from Katie Leamon is perfect and I can't believe it's taken me this long to finally dig them out for use (my excuse is that they are just too cute and I didn't want to waste them!). They definitely make tedious tasks bearable.
Finally, find a practice question bank online! There are loads if you just search on Google and practice questions are great for teasing out those gaps in your knowledge that need filling in during your next study session.
My sister made me this adorable Totoro earlier this year and he stays propped up on my desk, accompanying me every time I revise or study! He was just too cute not to share so I thought I would :)
