organised mess

to my surprise, today i realised that i have to organise when to do practice questions - as i opened a verbal reasoning book i realised it has many many practice tests.. which cannot be crammed into a single day's revision. i had to pause and rethink my revision timetable. its difficult to decide on what you need to do for the day when you have just glanced over the book's cover annd had no idea whats inside!!!! silly mistakes..
though knowing that there is more practice in the book just makes me anxious even more. would i have enough time to go through it all?
