General tips when working with science ACT practice• Don’t read unless you have to!

--If it says “According to passage…” or something similar

--If you can’t find the info in table or graph

• Make sure you are looking at the right figure or table: mark text!

• Be sure to review the column headings, row labels and/or axes on graph so that you can identify the correct one to use

• Don’t guess—you can find the answer!
