Hello everyone,

and welcome to my revision site.

Let me briefly introduce myself. I am Sanchez, a student studying in Hong Kong.

This site was created to enhance my learning whilst sharing my knowledge on subjects around the world.

If this site teaches you something, then I am definitely learning something.

As William Glasser said,

we learn.....

10% of what we READ

20% of what we HEAR

30% of what we SEE

50% of what we SEE and HEAR

70% of what is DISCUSSED with OTHERS

80% of what is EXPERIENCED PERSONALLY

95% of what we TEACH TO SOMEONE ELSE

May this inspire you to be a better learner..

** this site is created by a STUDENT (if you haven't noticed yet) so since you may not think of my 'information' as reliable, I will try to attach / list the sites or sources available that proves my point.

just a few acronyms you should know:

GCSE - General Certificate of Secondary Education (thats an exam)

IGCSE - International General Certificate of Secondary Education (that's an exam too....)

if there's anything you need or any comments you wish to make.. just email me at sanchezfacebook@gmail.com

=) Sanchez =)

Oct 2020 Update: I have recently realised that I have received some multiple emails with questions. I apologise for blanking anyone intentionally over the past few years. This website was created ~2009-2011 years (as you may have noticed from the reference links to the syllabi) I am now no longer a GCSE student, but am instead a student in the school of "life". While I am thrilled to have received some of your questions, I'm not entirely sure I'm qualified to answer anymore... I have left the site up in case you have found my notes useful over the years, or while e-learning your way through the pandemic. Stay strong and hang in there :)

Where I have referred to other sources, I have made reference to them in my pages. However, it would be unsurprising if those links no longer work. To that end, I wish you the best of luck with your studies and future endeavours.
