Transferology is the most specific resource available to see how credits may transfer prior to applying. Transferology is based on coursework that has been evaluated by UNLV in the past, so it is not official or comprehensive, though it is constantly being updated.
To use Transferology, create a free account (you won't be spammed), enter your coursework in the "Will My Courses Transfer?" tab, search for matches, and filter by the state for Nevada, where you can select UNLV. You are also encouraged to familiarize yourself with the information below. There are additional resources available for students transferring from an NSHE two-year institution.
