With only three weeks before the start of the fall semester, Final Draft is offering an eighteen-week trial for students at eligible educational institutions. Eighteen weeks should be enough for a semester. After that, students can purchase the software for $129—a discount of $120 off the standard pricing—and then regular upgrades for $99.
For as long as I can remember, the industry standard for screenwriting software is Final Draft. It might not be everyone’s favorite, but it is what everyone in the screenwriting game uses, even if it’s not especially good software.
Or you can just use an application that supports Fountain.
