If this is you, I have one sentence that is going to be important:
Expect the worst and don't expect any miracles.
The best you can do now is to get through the main stuff and do your best in the exam. Unless you've attended every lesson, done all the assignments and haven't fallen behind once, you will not get a top grade. And chances are that if you did all this work in the first place, you wouldn't be in the position of having to cram.
Here's a step by step guide of what to do when cramming. Use this guide if you have less than 24 hours till the exam:
- Get all your notes together and texts used during your course. Make sure you have a copy of the specification.
- Get a wad of plain paper or lined. It doesn't matter. Just get some paper. A pen helps too. Different coloured pens also help.
- Use your specification to get the heading of each topic and write one topic on the top of one separate page until you have a few sheets with headings on the top.
- Go through your notes and text and write down at least 5 points for each sheet.
- Once you have your points, get out a sample paper and a sheet of paper.
- Write down the questions on the paper with enough space to write down some notes under the question. If you want you can skip points 3 and 4 and use the questions to make points instead.
- Do everything as said above but instead, write down the questions you can find and answer each and every one of them.
- Condense these answers into key points and type them up onto the computer.
- Revise from these notes.
If you ever find yourself in this position then learn from this mistake. Write down exactly what it feels like and stick that note on the wall. It'll be a constant reminder.
I hope this helps but I do understand it won't help everyone. You learn in your own way. But remember this: You won't be able to cover everything so just go through the main ideas.
And good luck. You'll be needing it.
