The first part of the test will cover exponents, greatest common factor (GCF), and simplifying fractions. Here are a few helpful links to previous posts. Please look through these and refresh your memory on these concepts:
Exponents (here's a helpful post from the Transitional Math blog - ignore the questions and just check out the summary of exponents): http://tlsmath6.blogspot.com/2014/09/thursday-94.html
GCF: http://tlsprealgebra6.blogspot.com/2013/12/finding-gcf-through-prime-factorization.html
Simplifying Fractions: Just remember to keep "dividing down" until your fraction is simplified. You can also find the GCF of the numerator and denominator, and then divide the top and bottom by the GCF.
The second part of the test will cover simplifying expressions with exponents (please review your exponent rules - I've posted a helpful chart below from math-play.com) and scientific notation. For your questions on scientific notation, you will be asked to express a given number in scientific notation and then asked to express a number which is already in scientific notation in standard form.
Happy studying!
