i havent really had an assignment that required me 2 look 4 info about science or history.but i hav had 1 assignment that required me to look info but dat was out of a book so it doesnt really count.if this does count then wat i did was look in the text book look at the paragraphs and if it had any of the words i needed then i would read the paragraph.the results were pretty good and i got an A+
