On-Campus Resources for Dual Enrollment Students
Mountie Makerspace
A MakerSpace is a physical location where people gather to share resources and knowledge, work on projects, share ideas, and build; like a community center with tools. Students may use the Mountie Makerspace as a benefit of their normal Mt. SAC fees and tuition. Faculty and staff may also sign up for free. Community members must sign up through Community Education before becoming a Mountie Makerspace member.

The Mt. San Antonio College Library supports student success through knowledgeable and effective instruction and service to students, faculty, and staff by educating them to use appropriate resources and technologies for teaching and learning and by providing access to a comprehensive collection that supports the College’s curricula and that serves the needs of our diverse college community.

Writing Center
The Writing  Center is dedicated to helping Mt. SAC students across the curriculum improve their writing and critical thinking skills. We believe that our role is not to "fix" students' writing or guarantee a particular grade, but to guide them through a process of growth and development as writers. We believe that every writer needs a non-evaluating reader and that one-on-one, collaborative instruction is highly effective in meeting the unique challenges academic writing poses.
