Weezy, IMHO it won't be a waste of time. However, aside from my opinion, there's the question of whether you plan to attend a BSN program, either for your first nursing degree, or an RN-to-BSN in the future.
Keep in mind that many BSN programs require one or two general chem courses (w/labs). These schools typically require the chem credits for all
their BSN programs. Over the years, I've worked with many ADN-nurses who hadn't taken chemistry since it was not a pre-req for their ADN nursing program. When they finally decided to go for their BSN, they were shocked to discover that they had to take college chemistry courses before they could apply to the RN-to-BSN program of their choice. Some were really struggling with the difficulty of the class material, and with juggling the demands of the class, their full-time nursing jobs
, and their families. Many expressed regret that they hadn't taken chem when they had taken their original nursing prereqs, but they hadn't had any idea that they would ever need the credits.
Since you have the time now, I'd go ahead and take the class. Just make sure that the specific class you are taking is transferable to the BSN programs in your area.
