  • What do I do if I forgot my login info?
    If you've only forgotten your password, just click the "Forgot password?" link when you try to log in. You'll receive instructions on how to reset it. If you've forgotten the email you signed up with, send an email to (or message me on Instagram or Group Me) and I'll look it up for you!
  • When does my plan expire?
    I cancel all current plans the Saturday after the semester ends, according to IU's official Academic Calendar. Currently, all plans will expire Saturday, December 18, 2021. ***If you have a Free plan, you'll only ever be able to access material related to the first half of the course, but I keep your account active through the end of the semester so you can still use Finite Plus to study for the comprehensive final exam.
  • If I'm in D116/D117, can I keep my subscription through both courses?"
    Short answer: YES! If you're enrolled in D116, send me an email at to let me know and I won't cancel your plan at the end of the semester. Once you enroll in D117, I'll send you a link for an additional payment of 50% your original plan value (so $6 for Basic and $24 for Premium) to keep accessing the materials/e-tutoring behind those paid plans for an additional semester.
  • Do you offer private tutoring?
    I used to, but now that I work full-time and live in the Pacific Northwest, it became too overwhelming to allow everyone to book sessions with me. That said, if you'd like to inquire about my rates and availability for private tutoring, send me a message using the chat feature below or on Instagram (@finiteplus). I'm sure we could figure out a plan that best suits what you need to make it through this semester.
  • Where can I find all the study guides and cheat sheets?
    Click on the "Study" tab, then choose any of the four sections. The study guide for that section can be accessed via the button at the top of the page and any cheat sheets for that section will be linked in the box next to the practice test. Cheat sheets are also linked to the paper icon next to the title of each tutorial (not every tutorial has one, though, so keep your eye out!).
  • Can I get a refund?
    Unfortunately, no -- for the simple reason that I don't sell anything that can be returned. I sell my time and for you to gain access to and download materials that couldn't be unseen or undownloaded after issuing a refund. For that reason, I treat all sales as final. However, if for some reason I've really let you down and you think a refund is warranted, shoot me an email at and we'll work something out.

Our Story

Therin and Zach have been friends and filmmakers since their freshman year of undergraduate school. In the spring of 2018, as they were preparing to make their next film, they realized their video production skills would be put to better use teaching finite mathematics, a required course for all undergraduates at Indiana University. Because so many students struggle to successfully complete this course, and may end up paying tutors hundreds of dollars over the course of a semester, they set out to create an affordable service that would help students get an A in their finite courses.


Indiana University Class of 2018. B.A. in Media Studies with minors in Playwriting and Creative Writing. Therin is the lecturer and content creator of Finite Plus. He recently completed an MFA in Creative Writing at UNLV and currently lives in Portland, Oregon where he works as a claims adjuster.


Indiana University Class of 2017. B.A. in Media Studies with a minor in Spanish. Zach is the video producer of Finite Plus and is currently the owner of Lionheart Pictures, a video production company that creates high-end visual content for individuals, brands, and companies all over the country.


Indiana University Class of 2021. B.A. in Finance and Accounting at the Kelley School of Business. Max is the web designer of Finite Plus and is currently wishing you the  best.

Therin Alrik

Although he didn't pursue a degree in the subject, Therin has displayed a propensity for mathematics throughout his academic career. After completing his undergraduate degree in Media Studies, Therin moved to Las Vegas to pursue an MFA in Creative Nonfiction Writing at the University of Nevada, where he completed a book-length thesis and taught six sections of introductory and advanced composition. He now works as a claims adjuster for Progressive Insurance. Combined with his inclination for mathematics, this academic and professional background have given him the experience necessary to teach finite online.

Zach Watt

Zach Watt has an extensive background as a filmmaker and video producer, which began as an undergraduate student at Indiana University, where he worked as a freelancer and manager of the Learning Media Team at the Kelley School of Business. At the start of 2018, he began the next chapter of his career by forming Lionheart Pictures, a video production company that offers services for a variety of projects, including e-courses, commercials, and documentaries. He currently lives in Bloomington, Indiana with his wife Jorgi, cat Nala, and dog Titus. 

Max Weger

Max Weger is a Kelley School of Business undergraduate who has a lifelong interest in technology. Throughout high school, he had jobs in the Computer Science field at Indiana University and currently holds multiple positions in the tech field. His aptitude for technology and education in business has made him an asset to the Finite Plus team, and after completing finite at IU himself, he knows how useful an online supplemental course can be.
