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.

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). 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
"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.
