Best Algebra Review Book for Adults: Help Your Dad Prepare for University

[LSDwhat?]

Hello my dad wants to ingress University and he needs to recall all the basic Algebra stuff as he says he remembers basically nothing.

I checked amazon and from the ratings two books distinguish from the others with the rating.

What would you think would be best https://www.amazon.com/dp/0965911381/?tag=pfamazon01-20 ? or none

I recommend https://www.amazon.com/dp/0817636773/?tag=pfamazon01-20 by Israel Gelfand. This book was originally written for distance education, so it will be good for self-study. He also wrote Trigonometry and a few other other books at the same level.
