Did you know that CTREX Pro Subscribers can “bookmark” reviews for future reference?

While logged in, click on the star next to any title. This will save the review to your profile page. You can view your profile by selecting the icon with your username in the top-right.

Bookmarking has been available for a while now, but now you can create your own folders to organize your bookmarks into as many lists as you want. You can even print these lists or export their data.

Need to find a handful of titles on a certain topic? Create a new folder and move your bookmarks to it. The next time you need to compile a list, your old bookmarks will remain separate. Using this new tool, you can use CTREX to manage your research more flexibly.

Check it out, and let us know what you think! We're always looking for ways to improve the CTREX experience.

This well named app pulls you into the concepts behind the math equations, so they snap into your brain. Your job is to help Ruggles, a small furry space traveler, move from level to level by manipulating a number line, which is used to navigate through a vertical and horizontal axis.

The puzzles ask you to analyze and interpret graphs in order to predict real events while modeling the motion of physical objects. You learn to calculate slope, as well as develop a deeper understanding of the connection between slope and velocity. There are two major concepts: that the slope of a position-time graph represents the object's velocity, and that the y-intercept of the line represents the object's initial position. There are 75 levels. Created by New Jersey physics teacher Matt Blackman. We highly recommend this app, and hope to see more like it.
