Simple PCR is a chrome extension developed by Manan Shah that aims to revert PCR (Parent-Child Relationship) to its original state, where assignments do not show up repeatedly throughout the week. This extension serves as a temporary fix for the recent change in Harker's PCR system, implemented on April 24, 2015. It is important to note that the extension does not work on the month view.

With Simple PCR, users can enjoy a more streamlined experience with the PCR system. The extension eliminates the inconvenience of assignments appearing multiple times within a week, providing a smoother and more efficient workflow for users. By reverting PCR to its original state, Simple PCR offers a simple yet effective solution for those who find the new PCR system challenging to navigate.

Overall, Simple PCR is a useful chrome extension for Harker students who want to optimize their PCR experience. It effectively addresses the repetitive assignment issue introduced in the recent PCR system change, making it a valuable tool for streamlining workflow and improving productivity.
