# Learnist: Basic Algebra on the ACT and SAT

Expert Katie Cantrell over at Learnist offers a great look at the fundamental algebra concepts on the ACT and SAT exams. Refresh how to isolate variables, solve basic equations, and apply the order of operations on Test Day!

This video in particular covers several ways to conceive of variables, how to solve linear equations with fractions, and how to check your work to ensure that you have found the correct answer.

# Learnist: ACT Science and Data Representation

The Data Representation format on the ACT Science Test will ask you to understand and interpret information presented to you in graphs or tables. Occasionally there will also be charts, scatterplots, and diagrams.

As the video below outlines, it’s important to REALLY analyze all the data you’re given. The point of Data Rep is to determine your ability to pinpoint and extract conclusions from a series of data. 38% of the ACT Science passages will be in this format.

Making sure you have a strong understanding of the data will save you lots of headache when you read the questions. The questions will be so much easier if you spend just a few minutes focusing on the data. Check out tutor Jim Jacobson’s strategy for just how to do that in this video!

Need to see a passage in action? Sparknotes reviews some basic strategy, then shows you a passage exactly like one you’ll see on Test Day. Start with the intro, then when you get to the chart, you should glance over it to make sure that you know what’s being measured and that, in general, you feel comfortable finding information in the chart.

# ACT Science Test – where to start?

On Test Day, the ACT Science Test will always be the fourth test you’ll take. It will have 7 passages and you’ll have 35 minutes to complete them. Even if your knowledge of Science is limited, you can still get a great score!

Pacing is by far the most important aspect of the ACT Science Test. Don’t wait until two weeks before your test to get started. You will only have about 5 minutes per passage, so you may want to start by only doing 5 passages, allotting 7 min per passage. Once you can confidently do 5 passages with reasonable accuracy, work your way up to 6 and then 7.
