There are no limits to what we can imagine using the biological structure and function of our brain.

Our imagination is created by the laws of chemical reactions and quantum physics.

Therefore, there are no limits to what science can achieve and help us understand,

 BUT, there will always be questions, both scientific and philosophical, about ....

what we find out, what we can create, what we do with what we create, and, what we don't know or understand.

Secondary school, academy and college systems and my science website

UK Secondary School System in terms of science and chemistry - for pupils of ages 11 to 18

KS3 Science - mixture of biology, chemistry and physics for pupils aged 11 to 13 (Pupil Years 7, 8 and 9)

KS4 Science - a combined mixture of biology, chemistry and physics or three separate sciences for students aged 14 to 16 (Pupil Years 10 and 11)

KS5 Pre-university Advanced Level Chemistry for students aged 16 to 18 (Year 12 and 13 students)

Secondary school education in the USA to K-12 in terms of science and chemistry (some grade descriptions overlap)

Middle School 6th to 8th grade ages 11 to 14 US grades 6,7,8 science

Junior High School 7th to 9th grade ages 12 to 15 US grades 7,8,9 science - a combined mixture of biology, chemistry and physics

High School 9th grade to 12th grade ages 14 to 18, (9th to 10th grade ages 14 to 16) US grades 9,10,11,12 biology, chemistry, physics

Senior High School 10th to 12th grade ages 15 to 18, (11th to 12th grade ages 16 to 18) US grades 10,11,12 pre-university college chemistry

Secondary education in India begins after eight years of elementary education and is divided into two years of secondary education (classes IX and X) and two years of senior secondary education (classes XI and XII). Therefore the Indian secondary school system consists of Upper primary for pupils ages 11 to 13, Secondary for pupils ages 14 to 16 and Upper secondary for students ages 17 to 18

ICSE (CISCE) The Indian Certificate of Secondary Education (ICSE) is an examination conducted by the Council for the Indian School Certificate Examination, a private board of secondary education in India. It has been designed to provide an examination in a course of general education, in accordance with the recommendations of the New Education Policy 1986 (India), through the medium of English. The examination allows secure suitable representations of responsible for schools (which are affiliated to it) in their states or territories. ICSE includes for classes IX, X (Environmental Science and Science (Physics, Chemistry, Biology)) and XI and XII (chemistry).

There are various Indian Examination Boards: At the end of the secondary phase (class X), students take a set of externally administered examinations from either a state or national (All-India) examination board. Students who pass the secondary examinations earn a certificate usually called the Secondary School Certificate or SSC. These students are eligible for senior secondary school. Secondary qualifications may also be known as: Indian Certificate of Secondary Education (awarded by CISCE), Secondary School Certificate (awarded by NIOS), Secondary School Leaving Certificate and the All-India Secondary School Certificate (awarded by CBSE).

After two years of senior secondary school, students are again examined by their school’s affiliated board and, if successful, awarded the Higher Secondary (School) Certificate (HSC/HSSC). There are also examinations administered internally by individual secondary schools at the end of class XI.
Higher Secondary Certificates may also be known as: Intermediate Certificate (some state boards),  Pre-University Certificate (some state boards), All India Senior School Certificate (CBSE), Indian School Certificate (CISCE) and Certificate of Vocational Education (CISCE).

Australian secondary school system

Junior secondary school years 7 to 10 for pupils aged ~12 to 15 studying science as a mixture of biology, chemistry and physics as part of a Year 10 School Certificate

Senior secondary school years 11 and 12 for students aged ~16 to 18 studying chemistry as a specialist pre-university advanced level as part of a Senior Secondary School Certificate of Education

TOP OF PAGE and main index

Above are links to the main sections of Doc Brown's Chemistry's website, these in turn link to other sub-indexes from which I hope you will bookmark useful and relevant links for your science course. At the top and bottom of all revision notes pages of Doc Brown's Chemistry are more detailed sets of navigation bar buttons to which you should make yourself familiar. The Google search engine is dedicated to Doc Brown's Chemistry's website putting in 'anything of interest' and you can put in multiple words to get the best page match from Doc Brown's website.

"Doc Brown's Chemistry" is a website designed for science students studying GCSE Biology, GCSE/IGCSE Chemistry, GCSE Physics and Advanced Level Chemistry. My website covers the current science syllabus specifications from AQA, Edexcel and OCR examination boards. The website also covers International IGCSE science, biology, chemistry and physics courses.

This science revision e-learning  website includes notes & quizzes for chemistry, but now includes some biology and physics notes too AND lots of 'unofficial' revision summaries for ALL the current GCSE Sciences (links below). The new GCSE specifications starting in September 2016 are covered completely by Doc Brown's Chemistry plus biology and physics revision notes and specification summaries.

The science, biology, chemistry and physics notes are generally aimed at 14-16 year old students and the UK GCSE/IGCSE notes roughly fit in with US grades 8-10.

I hope these web pages of 'Doc Brown's Chemistry'  help your studies! and a warm welcome to the HOMEPAGE of doc b's "Chemistry Online" revision website. This was my millennium 'teaching & learning' project and Doc Brown (teacher) has been online since 2000! Its a big SCIENCE WEBSITE to get to know from a retired CHEMISTRY teacher (and some physics and general science for teaching and learning purposes), SO, use the appropriate INDEXES and Google custom 'Doc Brown's Site' SEARCH too! 'Doc Brown's Chemistry' (all material © Dr Phil Brown 2000 onwards) has lots of  science revision notes & quizzes, mainly an e-learning website for chemistry, but includes some biology and physics too AND lots of 'unofficial' revision summaries for ALL the current English GCSE Science courses
