 \n2.They won't ask you for units in your answers on the calculation questions,but they may on the short /longresponse questions.However,looking at the units may give you a hint as to which term in the equation you arebeing asked to find.  \n3.Don't round your work until you get to the answer!  \n4.Read the directions carefully for each question you answer.The question will indicate whether you should roundto the nearest whole number,tenth,hundredth,etc.If you round to a different place,your answer will be scoredas INCORRECT!  \n5.With your four function calculator,there is no exponent function.You must use the “old school”method ofmultiplying a number by itself to square it.  \nExample:2³=2×2×2=8  \n6.You must be able to convert back and forth between scientific notation and whole numbers.Examples:  \n·5.1X10³=5100  \n● 6.2×10⁻⁴=0.00062  \n·442=4.42×10²  \n·0.008=8.0×10⁻³  \n7.If you want to “get rid”of an exponent on the variable you are solving for,take each side of the equation to thepower of the inverse of the exponent  \nExample:X¹³=5 can be adjusted to (X¹3³=(5)³to isolate“X”and further simplified to X=125  \nThe“Grid-In Chart”  \nAcceptable Grid-In Responses:  \nAP Biology Formula Sheet-Page 1  \n\n| Statistical Analysis and Probability  \u003Cbr>Standard Error  \u003Cbr>Mean  \u003Cbr>Chi-Square  \u003Cbr>Standard Deviation  \u003Cbr>Chi-Square Table   |  |  |  |  |  |  |  |  | S=sample standad deviation(ie,the sample based  \u003Cbr>estimate of the standard deviation of the population)  \u003Cbr>X=mean  \u003Cbr>n=size of the sample  \u003Cbr>0=observed individuals with observed genorype  \u003Cbr>e=expected individuals with observed genotype  \u003Cbr>Degrees of freedom equals the number of distinct  \u003Cbr>possible outcomes minus one.   |\n| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |\n|  | Degrees of Freedom   |  |  |  |  |  |  |  |  |\n| P   | 1   | 2   | 3   | 4   | 5   | 6   | 7   | 8   |  |\n| 005   | 3.84   | 5.99   | 7.32   | 9.49   | 11.07   | 12.59   | 14.07   | 15.51   |  |\n| 001   | 6.64   | 9.32   | 11.34   | 13.28   | 15.09   | 16.81   | 18.48   | 20.09   | Metric Prefixes  \u003Cbr>10⁶  \u003Cbr>M  \u003Cbr>mega  \u003Cbr>10³  \u003Cbr>k  \u003Cbr>kilo  \u003Cbr>10²  \u003Cbr>centi  \u003Cbr>C  \u003Cbr>10³  \u003Cbr>milli  \u003Cbr>m  \u003Cbr>10⁶  \u003Cbr>micro  \u003Cbr>μ  \u003Cbr>10⁹  \u003Cbr>nano  \u003Cbr>n  \u003Cbr>10²¹²  \u003Cbr>pico  \u003Cbr>P   |\n| Laws ofProbability  \u003Cbr>IfA and Bare mutually exchusive,thenP(A or B)=P(A)+P(B)  \u003Cbr>IfAand Bare independent,then P(Aand B)=P(A)x P(B)  \u003Cbr>Hardy Weinberg Equations  \u003Cbr>p=frequency of the dominant alele  \u003Cbr>P²+2pq+4²=1  \u003Cbr>ina population  \u003Cbr>p+q=1  \u003Cbr>q=frequency of the recessive allele  \u003Cbr>ina population   |  |  |  |  |  |  |  |  |  |\n| Mode=value that occurs most frequenty in a data set  \u003Cbr>Median=middle value that separates the greater and lesser halves of a data set  \u003Cbr>Mean=sum of all data points divided by number of data points  \u003Cbr>Range=value obtained by subtracting the smallest observation(sample minímum)from the grentest(sample maximum)   |  |  |  |  |  |  |  |  |  |\n\n3   \n2  \n13  \n10  \nAP Biology Formula Sheet-Page 2  \n\n| Rate and Growth  \u003Cbr","cbCaidjZ05Sr0LW9","https://ap.wps.com/l/cbCaidjZ05Sr0LW9","pdf",5695084,23,"English","# Test format overview\n## Section 1 timing and question types\n## Section 2 timing and question types\n# Calculation grid-in tips\n## Diagram-first strategy\n## Units and rounding rules\n## Calculator and exponent methods\n## Scientific notation conversions\n# Grid-in chart and formula sheet\n## Statistical analysis and probability\n## Hardy-Weinberg equations\n## Rate and growth\n## Water potential and solute potential\n## Surface area, volume, dilution\n# Key equation references","[{\"question\":\"How long is the AP Biology exam and how is it divided into sections?\",\"answer\":\"The exam lasts about 3 hours and has two sections.
