Recently, an SAT tutor reported a story of list-building success:

After an initial vocabulary assessment, I assigned a new student the task of building a list of trouble words using your list builder. I'd assumed that we'd start learning the words together after he'd made the list, but then, I realized that by the time he'd got the list built, a lot of the word learning was already done. 

We're thrilled to get notes like these and also thrilled to reply that, Yes, it's true that the tactile activity of list-building — typing the word and then reading and selecting the definition and usage examples — gives a student's brain a great head start toward learning.  

But be careful. As engaged as the student may be with the words on the list today, list-building does not ensure that the student will remember the words a week from today.

This isn't the student's fault. It's just biology — our brain is programmed to forget information we don't need or use, and we have to keep reminding it of what we'd like it to keep around. (Think of a teenager finding his mom in the process of throwing out a threadbare jean jacket. "Hey," we have to tell our brains over and over again. "I need that!")

The good news is that when you're learning words on, we take care of the reminding for you. Through repeated exposure and spaced repetition, we're in constant communication with your brain, ensuring that you learn words in the fastest, smartest way possible.

In other words, building a list of SAT words you need to work on as a Vocabulary List not only gives you a fantastic head start, it provides you with the tool that's going to get you to the finish line.
