understand biology
How to understand and answer Hardy-Weinberg Questions - A-level Biology. Remember to look out for questions where they give you a dominant phenotype frequency -for instance Huntingdons disease, where the frequency of the sufferers is 1 in 100000 - therefore q squared (recessive allele phenotype) is 99999 in 100000.

DO NOT LOOK at the question and then look at the data to answer the question.
Look closely at the graph or table
look very carefully at the axes - have they plotted mean or rate or time, mass/volume or concentration ?
can you see range bars ?
In a table what range is in the replicates when you compare to the mean ?
what trends can you observe ? then think about what principle of biology is being shown by the the trends.
How would you explain the highest value, the lowest value, the point at which the line crosses the x axis, how would you explain the largest range, how would you change the experiment to reduce the spread in the data ?
Once you have a coherent understanding of the trends - only then look at the question.

Each class is specific to an exam board and year group
“The focus the sessions have on understanding biological concepts and how to correctly answer past paper questions has really helped me. Through actively attending the group tutoring sessions my Biology grades are quickly improving from Cs to As.” - Eloise Brown (and yes she got an A!)
