I've been actually studying math properly. I got Stewart Calculus Early Transcendentals 7th textbook and solutions book. Been tackling it one problem at a time until I feel I understand. I have a binder full of fine graph paper where I do all my work Kind of sad I could have learned most of what's in there in AP Math as a teen but alas. At least i am doing it now. I hope to go beyond too and use it to enrich my understanding of fields like physics..
