The other route, though less common, that some students take is simply purchasing the Holt Online Learning program themselves, even though it is not necessarily required to complete their desired course. Many students report gaining a better understanding of their course material with the additional assistance provided through the Holt Online Learning platform. The online programs can help certain students that might learn differently than other students in their classrooms. These online programs tend to provide more interaction, case studies, and real world applications of the course materials than their printed textbook counterparts. The Holt Online Essay Scoring System is included within several subjects and sections of the Holt Online Learning platform. This essay scoring application is particularly popular among students and instructors, mainly due to its ease of use and ability to critique essays. Additionally, Quantum Artificial Intelligence Tutors are yet another online service provided by the Holt Online Learning platform. Holt Online Learning, along with the platform's corporate foundation originally represented by the Holt, Rinehart and Winston company, has recently undergone some upgrades and additions. As a result of these recent changes, the Holt Online Learning program is now officially known as ThinkCentral. Think Central can be accessed by going to the new website address located at ThinkCentral.com (previously located at go.hrw.com). Some "online versions" of textbooks published by Holt, Rinehart and Winston and McDougal Littell are still accessed through my.hrw.com, which is the Holt McDougal Online program.
