Science Revision: Structured Tutorials for GCSE.

A structured series of 2-hour tutorials covering the most frequently examined areas of the GCSE syllabuses. These tutorials are designed to span the 8 consecutive fortnights leading up to the May examination period. The tutorials are batched in threes: the first tutorial in each grouping covers the subject topics in outline and is designed to highlight areas that need to be revised over the coming week. Revision progress is checked one week later in the second tutorial by tackling selected questions from past papers. The third tutorial takes the form of a 1hr practice exam, followed by the marking of it according to the official mark scheme. The use of a structured revision timetable in this way is very beneficial to the student: it is our confirmed experience that revision should be started as soon as possible after the Christmas break.

Cell Structure: Compartments and Organelles
The internal structures of plant, animal and bacterial cells: the what, where, why and how of basic cellular function. We start our revision by recalling that yeast is more like a little cow than a big bacterium!

Photosynthesis, Respiration and Decomposition.
6CO2+ 6H2O -----> C6H12O6 + 6O2
C6H12O6 + 6O2 -----> 6CO2 + 6H2O
C + O2 -----> CO2
And don't forget it!

Atomic Structure and the Periodic Table
All atoms want to be Noble. We revise electron shells, ionic and covalent bonds, groups and periods, reactivity. Just why is there so much nitrogen in the atmosphere?

Metallic Bonding and conduction.
Metallic bonding, free electrons and the conduction of heat and electricity. Alloys, insulation and electrical resistance.

Carbon Chemistry.
Making sense of all the meths, eths, props and buts, the anes, enes and ynes. Fractional distillation and cracking. Polymers.

Genes, Alleles and Proteins.
Cells were making polymers long before plastic was invented! DNA and protein as polymers. Enzymes and Antibodies. Natural Selection acts at the molecular level.

The Generation of Electricity.
The carbon cycle and global warming. Fossil fuels and cement. The alternatives of wind-, tidal-, hydroelectric-, geothermal-, solar- and nuclear- power. Radioctivity.

The Conversion of Energy.
The various types of energy and their interconversions, calculations and formulae, the conservation of momentum. The laws of motion.

Final Revision Tasks.
The last two tutorials are dedicated to the examination timetable itself. The timing and dates of papers will determine the final revision timetable; the well-prepared student will concentrate on exam performance, not last-minute revision!

Molecular Biology Tutorials.

These are 6x tutorials, i.e. each tutorial can be adequately covered in a block of 6 tuitions (that's one a week for the summer holidays). See also the Biochemistry series of tutorials for a much more advanced coverage of this GCSE module.

DNA makes RNA makes Protein!
An introduction to the 'Central Dogma' of molecular biology.

How do Proteins Work?
An introduction to the world of protein synthesis and degradation, cell cycling, enzymes, mutations and diseases.

How do Antibodies Work?
An introduction to immunology.

How do Antibiotics Work?
An introduction to infectious disease, the nature of bacterial cell walls and the problems of virulence and resistance.

How do Viruses Work?
An introduction to virology using HIV-1 as an (atypical) example.

How do Vaccines Work?
Influenza: vectors and pandemics, antigenic drift and shift, T cell responses and immunolgical memory.
