ALEKS concerns

We are using ALEKS in a 40 min lab that meets off days of a block scheduled 80 min algebra 1 class.  All was good at the beginning, but I think the lab is starting to get a little behind the class.  It's good for them to practice the basics, but some of the objectives are things like multiplying decimals that I'd like to be able to let go.  I am going to work with ALEKS and see if I can change this.  Does anybody know of a self directed practice site that allows me to align the objectives with the class?  I know about Khan Academy, are there any others to consider?
