If I decide to go from TT7 to LOF, can I move from TT7 to LOF Beginning Algebra? or should I go to Pre-Algebra with biology? and is this enough of science to use it for science? I looked for this answer and haven't come up with one yet. I realize LOF Pre-Algebra is new.
I have reasons for possibly making this change, one of them being my budget and the reasons we like TT7 (using the DVD's) changes next year anyway.
Thanks for any input!:)
