I would like to do a quick survey,what 1st yr college(or last yr hi-school) calculus textbooks did u guys used?

My myself and my younger brother studied Apostol's calculus vol 1 for HK A.Level Pure Math(HK grade 12 and 13)

I also tried Rudin's Principle of Mathematical Analysis but honestly I found it very hard
