I will be honest. Nursing school is quite difficult. I can't count the times where i felt frustrated and felt like giving up! However, at the end it is definitely worth it especially if you're someone who likes to help and feel compassionate for others.
When I started my Associate's Degree in Nursing, I found it a bit difficult and there was so much to learn: different diseases, medications, medical terminology, care plans. What made it easier for me was taking notes of what was discussed in class, going over them at the end of the day, and researching any terms/medications I didn't know. This helped greatly during both my Associate's and Bachelor's.
If nursing is a career you'd like to pursue, that is definitely my best advice on getting through school. Good luck and best wishes!
