Going to college can sometimes feel like a series of tough decisions. Not only do you have to take standardized tests like the ACT or SAT, you also have to decide which colleges to apply to and write (practically) a million applications!

After all of that, picking your major sometimes feels like the easy part. But not so fast! Many schools offer a variety of majoring opportunities, including a degree path referred to as a double major where you concentrate in not one, but two different subjects.

This guide will take the mystery out of what it means to double major! We’ll explore the ins and outs of the degree path, including:

• Defining what a double major is...and what it isn’t,

In 2024, major changes were made to the reading and math sections of the SAT. The SAT shifted to a fully digital format, reduced the exam’s total run time, and dropped the question count significantly in both exam sections. 

With these changes also came some necessary changes to how your understanding of certain concepts is assessed on the SAT. That means that some question types that appeared on the 2016 SAT aren’t on the new digital SAT, and some question types that appear on the new SAT weren’t on the 2016 SAT. 

In this article I’ll give you the rundown on how SAT analogy questions have evolved on the 2024 digital version of the SAT, and how they’re different from the 2016, paper-and-pencil SAT.
