I have a question to y'all lovely nursing students. Need to vent and get it off my chest.

I've been at this since Fall 2018 to become a nurse and I've achieved getting into the LPN nursing program. I'm in my second semester and in currently Med Surg II with clinicals and retaking Pharm along with retaking the school's one prereq of Bio 101 for their LPN and RN program which is the bio that covers the fundamentals of life and a hint of genetics.

I noticed in all 3 classes this semester starting since exam 1 of I'm not making good exam grades. They're always between 62-69% and if I'm lucky, a 70%. The nursing programs text grades requirement for LPN is 75% and above. My total grades in each of the classes are two B's (Med Surg II and Pharm) and 1 C (Bio 101) currently. I've been in multiple heavy classes before and had no issues. I've also had no whole semester off, only the normal short breaks between semesters and been going every semester since Fall 2018.

I'm 35, married with 15 year old twin son's. I'm dual licensed CNA and ASCP Phlebotomist. I've cut my jobs since last year down from part time to PRN to have more time towards classes, studying and homework during weeknights and weekends. For an hour or two on weekends, I'll take a break from homework to spend time with family if we have something planned or have me time in doing something I enjoy.

I have huge numbers of handwritten note cards and drug cards I've studied for these exams based on their study guides. I even go to a biology tutor weekly and review with my nursing instructors and director herself on the Med Surg II exams. I do have test anxiety and the program and my one pre req follow my extended exam time request from our school's disability office. I use just about all my time in taking the exams without rushing.

I know this stuff. I really do. But when I apply it to paper, it has been making me doubt myself sometimes. In clinicals, anything hands on clicks like second nature where anything I apply from what I've learned in lectures makes sense to me in my hands to do on my patients and charting it.

Is there anything I'm doing wrong? Overthinking it makes sense which I've caught myself doing before and end up going, "oh, I need to stop changing my answer often when I know it's right". I recently found that writing on my tests works cause I pull out all the knowledge I know out on scratch paper as each question comes. It surely shows them I know but what is happening at this point? Could it be me mentally of holding myself back somehow at test time? Could be I'm burned out after going at it for years?

Before going to classes and taking exams, I went as far to take CBD oil broad spectrum to calm any nerves that are jittery or fears that I'm not aware of. Anyone else has been feeling like me or has gone through something like this?
