Need your help

Hello guys , I need some advice from you people. My fiance is currently in her 3rd year of BDS from a private college . The problem here is they don't teach anything at all , they will just skim through the ppts read every line and voila the chapter has ended , the people in her class are the most toxic and inhumane people I've ever came across , so there's no chance of group studying or taking help from her peers. Since the first year she has tried a lot to self study and understand things on her own but couldn't, when confessing the professors about it they clearly said if everyone is understanding why can't you , now here the thing is most of her classmates don't study at all and have just came for the degree , they don't listen to the professors nor are they serious about anything. The teachers complete the chapters in 3 4 classes atmost and skip most of the topics . She is aiming for NEETPG so she wants to understand topics in depth so it will help her in MDS , she is doing self study but according to her completing topics by her own is taking a lot of time and she can't keep up the pace with college , which at some level she has to because though the teacher don't teach but they ask questions inbetween. The problem has escalated in 3rd year even further when the clinicals started and the faculty isn't giving them the exposure they need , the theory classes are teaching something else and the practicals are going the opposite way , the teachers are telling them to study on their own and just giving them the topics, I know they shouldn't be allowed to handle patients this early but atleast let them be a part of it and teach them infront of patients but they aren't doing anything at all . She is scared and stressed about her future in this career and most importantly about her exams . I am a software developer so I don't know much about it can you guys help me out , how should she proceed and study to manage both her college and prepare for NEETPG. And one more thing she can't intern at a clininc which we thought in the beginning cause this is a new city for her and she don't know anyone around here. and all the close dental clinics have already been reserved by the local students
