Lists cannot provide all possible meanings for the words they provide. Only a dictionary can do that, and SAT vocabulary questions often turn on secondary or even tertiary meanings.
When you learn from a list, your memory of the order in which the words appear in the list can interfere with your memorization of their definitions.
Furthermore, this “false context” of order is the only one a list can provide. “True contexts,” such as “words that all mean hatefulness,” are impossible, since you can’t reshuffle a printed list.
There’s a tendency to look at any list as “everything you could ever possibly need to know,” and thus it’s tempting to eschew all other methods for building vocabulary. In that case, you’re only as good as your list. Our list is as good as it gets, but it’s still only 92 words.
Even the best list can only help you learn the words it contains, since you’re learning individual words.
