I've always been a procrastinator, so I totally understand your hesitation. I'll tell you this much, I was still a procrastinator when I started my first semester of NS. However, I got a massive slap in the face by failing my first exam because I didn't allot myself enough time to really digest the material (it's not enough to just memorize, you have to be able to apply the information in "real life" situations and questions on real life situations and my biggest hates "choose all that apply", or "all the answers are correct, chose the MOST correct" are huge in NS). And then came my first clinical....and the chart study that went with it. When I began the paperwork at 8pm and finished it at 5:30am the next morning just in time to start clinicals at 6am. It sucked, and that kind of negative conditioning really helps you get over the procrastination thing fast!
What works for me is to allot myself a time slot every single evening. 3 Hours (for my it was 5-8pm because that was when my hubby could watch our daughter) to work on nothing but nursing...reading, writing, etc. At the end of that time, I could take a break for awhile to relax, and then I made myself go back to work. When something was finished, I rewarded myself with something. You'll want a planner if you don't already use one, because if your school is like mine, times for things will be all over the place (clinicals, exams, meetings, sim labs) and you have to keep track of so many different things. I just wrote my study time in there too, and when I was done, I got to check it off and it made me feel good to be able to do that. You'll find what works best for you, I'm sure! :) Just try not to feel too awful if you bomb that first test, it's not the end of the world and it won't mean the end of nursing school............just make sure you don't bomb any more than that! Good luck! :)
