I'm so confused . On the biology section they have the formula p^2+pq+q^2 in the ecology section apparently it's given in person and u have to find the square root of the number .... People who have taken this exam , is there square root problems ? I usually use the calcultor however I know square root of 4 , 10 and so on the common numbers .... As well as sin and cosine I know fraction like sqrt3/2 should I know the decimal form of it or no ? Please if someone can break down the calculation parts on the exam that I should learn and memorize to do
