Welcome to Seldeen's Vocab!

We are the best value and highest quality vocabulary preparation service on the internet. We have been online since 1998 and have helped over 10,000 students improve their vocabulary performance on the most important academic test in the United States: The SAT.

The Essential 150 Vocab Series
The key to our success has been getting test takers to learn the most important words right away. The Essential Vocab Series is 150 of the most often missed words on the SAT. The College Board knows that students consistently get these words wrong. That's why they keep asking them. We give our students concise definitions specifically developed for use with the SAT standardized test. We email students specialized study guides to get the most out of their study efforts. These no-nonsense tests tell students what they need to do and offers a broad perspective about the value of clear communication. Although the 150 can be crammed in a weekend, most students will take 4-8 weeks to complete this portion.

The Complete 1000 Vocab Series
While the Essential 150 Vocab Series is where most students will get the greatest boost on their SAT score, we encourage all students to continue expanding their vocabulary with our second series of important SAT words. Words on this list frequently appear on assessment exams. It is really all the words that a student ought to study. This series takes three to six months to complete at the usual pace.

The Word Survivor Online Game
Once you think you know your vocabulary, put it to the test! Word Survivor pits two live players in real-time head-to-head competition. Students try to become a vocabulary master by revealing holes in their opponent's vocabulary while demonstrating their own dominance of words - Addicting as studying can be.

Focus List Customizable Word Help
Focus words are a customizable feature that allows students to collect words they find difficult and spend extra time learning them. Soon students will be crossing words off this list as quickly as they put new ones on.

Ultimate 5000 Word Series
Some people just can't get enough. For them, we offer nearly 5000 important vocabulary words to memorize. We don't necessarily recommend this for all students, in fact similar lists are available for free on the internet. However, the Ultimate 5000 Word Series is here if you want it and we mention it mainly to emphasize that our vocabulary preparation service is more than just a list of words.
