Hello ~ 37?? No worries...I am 44 now and started my pre-req. for nursing school about 1.5 years ago. I was an average student in H.S. & didn't do so well taking some college courses here & there. But I didn't have drive or emotional support. The one (of many new qualities) thing I have discovered about myself is that I CAN do anything I am motivated to do. You sound like you have a positive outlook & go getter attitude. This will help you tremendously through your classes. I put everyone's dreams 1st & supported them to get theirs. Now it is my time, no matter what age (esp in nursing) it can be done & done well. You will amaze & surprise yourself with your dedication & how smart you truly can be. Use your knowledge of living life longer than others, experience helps with a broader knowledge & knowing how to study. If you need any advice with pre-req classes please ask. I have completed mine, & am in the process of applying now. It can be done! Good luck to you & enjoy it.
