I literally have an exam in two days and the books i refer to have shit ton (apologies for the language) texts and paragraphs WHICH literally makes me want to cry and make me hopeless and makes me doubt my capabilities (frustrations in a nutshell and im a med student so you can guess the pressure). I really appreciate your hard work into making huge concepts seem like a pie. Im so glad i stumbled on your channel Literally godsent + life savor (in literal sense) [apologies for the rant but thank you genuinely] Hope you are blessed 😭❤️

I totally sympathize with you on everything 😂 I too had a hard time studying anatomy from textbooks during medschool. I started this channel to hopefully help other struggling visual learners. It makes me happy to hear that you're finding it helpful! You'll be just fine, keep pushing through
Helping me a lot bro for revision ❤️
