It may sound silly, but I’m currently using the Kaplan Learning anatomy coloring book and it’s really helping
Try Last’s anatomy, buy Netter’s for visualization, download aclands videos from torrents if you want or get a subcription on wolters kluwer website. Greys student edition is also a great book, if you live in india BD Chaurasia is good book for UGs
KLM or Gray’s anatomy but for GI anatomy, BD Chaurasia is good.
