Finally some maths brain cells in my head

Today, I did my first maths paper after three years of not touching a calculator.
Just to make it sound more impressive, I did my first Cambridge maths paper today!
Yes, that's better.

And I think I did pretty well. Hehe.
You couldn't imagine how much effort I had put in just for this paper.
I constantly bugged my supervisor, did all the past years (and did them all over again before exams), read the textbooks, asked the engineers.

I even wrote down notes like:
1. 1 billion - 9 zeros, 1 million - 6 zeros.
2. Draw the diagram with pencil, make it at least half a page.
3. Double check the answers.
...
...
...
20. Look at your calculator while typing in the figures. DUH.

Now you can imagine how nervous I was before my exams.
I couldn't even sleep the night before.

Well that usually happen. Because I never sleep the night before exams.
But this time I made a point to have a full 8-hours sleep so that I can have an effective, and hopefully a mathematically-effective brain during the exams.
Yet still, I couldn't sleep -.-

But it's all worth the effort.
YEAH!
YEAH YEAH!
YEAH YEAH YEAH!

Just one thing.
Because I have put in extreme effort in this paper.
I kind of seriously neglect the other two papers.
And I mean SERIOUSLY, chronically neglect the other two papers.
Now I need to cover four subjects in 6 days.

Wish me luck.
As I need it a lot.

God.
Please grant me photographic memory.
Just for 6 days.

And I don't mind paying.
