Edexcel Salters Horners Physics - Analysis And Evaluation

Has anyone done the practical and the analysis&evaluation for the lemon cell experiment to measure internal resistance and E.M.F?
Could you please let me know on the stuff i need to concentrate on, that are easy to lose marks. Any other advice/tips, feel free. Anyone that has a link to clip that could show the actual experiment walk-through including the recording and measuring? - Would be great.
Thanks In Advance...

Criterion

A1: Produces a graph with appropriately labelled axes with correct units
A2: Produces a graph with sensible scales
A3: Plot Points accurately
A4: Draw lines a best fit (either a straight line or a smooth curve)
A5: Comments on the trend/pattern obtained
A6: Derives relations between two variables or determines constant
A7: Discusses/uses related physics principles
A8: Attempts to qualitatively consider sources of error
A9: Suggests realistic modifications to reduce error/improve experiment
A10: Calculates uncertainties
A11: Provides a final conclusion
Maximum Marks for this section: 11 Marks
