　　The most successful students are those who use large college edition dictionaries with about 100,000 words but do not use them too often.

They use dictionaries more for writing. If they are not sure how to spell a word, or divide it into syllables （音节）, they always use a dictionary. Also, if they think a noun might have an unusual plural form or a verb might have an unusual past form, they cheek these in dictionary.
