Features & Capabilities

USB helps you plan your semester schedule before or during registration. Pick your courses, see them on a weekly calendar, and know straight away if two sections overlap or if you are missing a prerequisite.

WHAT IT DOES

  • A weekly calendar of everything you have added, with morning, evening and full day layouts.
  • Conflict detection before you add a section, not after.
  • Prerequisite checking on every course, with a breakdown of what you have passed and what you still need.
  • Labs and tutorials stay attached to the course they belong to, so you cannot half-add a pair by accident.
  • Elective slots you fill from the right elective group, with your completed hours counted as you go.
  • Save named versions of a schedule and switch between them.
  • Export the calendar as an image, or as text you can paste anywhere.
  • Full Arabic and English interface, right to left included.

TWO WAYS TO USE IT Free mode needs no login. Choose your major and the extension loads that major's study plan along with the university's public timetable. Sync mode reads your own study plan from the university portal after you log in yourself, so it knows what you have already passed and what is left.

YOUR DATA STAYS ON YOUR DEVICE No account, no server, no analytics. Everything the extension reads is stored locally in your own browser, and nothing is uploaded anywhere.

This is an independent student project. It is not an official university product and is not affiliated with or endorsed by Mustaqbal University.

Is USB-University-ScheduleBuilder Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

USB-University-ScheduleBuilder requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

USB-University-ScheduleBuilder is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
