What advice can you offer me regarding my school's spelling bee which is on friday? i'm in the 6th grade and have to study 6 and 7 and 8

Not exactly sure about what it is you have to study "have to study 6 and 7 and 8".However here are a few pointers : 

-Make flashcards of the words you have to study

-Try to write out sentences using those words to help you memorize them-Associate those words with yourself make a funny story out of them. (humans tend to remember humorous things better) 

-You can also use online tools, there are many sites in which you can input the words and the site will make games out of those words. (I do this before every English vocab quiz I have :P) It really helps. 

When it comes your turn, always take every option offered, even if you're sure you know the word. If the say the word is "torture," ask for a definition, and ask them to use it in a sentence. It might be "someone who spear fishes at night with a light source. It was low tide on the island, and a lone torcher picked his way along the reef."
