Requirements Grade B at GCSE in Additional Science OR Biology C in English Language C in Maths on the Higher paper Our results Summer 2015 • 98% of students achieved a grade in A2 biology (45 students) • 27 % achieved grade A or A* • 67% achieved grade A*-C Work load and help • Usually 2 teachers; 1 for 3 hours (this may be split into a 1 hour) and 2 hour lessons and 1 for 2 hours per week • We expect you to do approximately 2-3 hours of work per week out of school • Internal assessment after every topic • Class sites on the MLE with web links, power points and past questions • Offer drop in sessions for help to all • Are available for 1:1 assistance when needed • We will contact parents if we have concerns Text Books • A text book can be bought in September (AS - £20/ A2 - £40) • Revision guides at a discount price. (£5) Specification at a glance Subject content 1. Biological molecules 2. Cells 3. Exchange 4. Genetics 5. Energy transfer 6. Responding to change (Homeostasis) 7. Population genetics 8. Control of gene expression AS : 2 exams units 1-4 on both papers 1 hour 30 mins each paper A-level : 3 exams, 2 hours each paper 1 units 1-4 paper 2 units 5-8 paper 3 units 1-8 including practical skills plus an essay. Practical Skills • A bigger emphasis on practical skills through the course. • 12 mandatory practicals, which are teacher assessed. • 15% of paper 3 for A-level will draw on the skills gained throughout the course. • Students will be awarded a pass or fail for practical skills, a pass will be shown on their final certificate. AS Required practical's 1. Investigation into the effect of a named variable on the rate of an enzyme-controlled reaction 2. Preparation of stained squashes of cells from plant root tips; set-up and use of an optical microscope to identify the stages of mitosis in these stained squashes and calculation of a mitotic index 3. Production of a dilution series of a solute to produce a calibration curve with which to identify the water potential of plant tissue 4. Investigation into the effect of a named variable on the permeability of cell-surface membranes 5. Dissection of animal or plant gas exchange or mass transport system or of organ within such a system 6. Use of aseptic techniques to investigate the effect of antimicrobial substances on microbial growth Mathematical skills and handling data • At least 10% of the marks will require the use of mathematical skills and will be at least the standard of higher tier GCSE maths. • Most of these will be in the first year. • E.g. ratios, percentages, rearranging equations, rates, geometry. What do our students think? Teachers are supportive and always willing to help. By far my favourite subject. The most interesting subject to study at home.
