Transcript A-level-Biology-Presentation-2016

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)

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.
