Getting MCSA Security Need Feedback

I decided that I am going to take classes at local school for mcsa security . I have been working in the field for the last 3 years , have my undergrad in MIS , just need some certs with my undergrad.

I tried the self study method and for some reason that didn’t work as some days work schedule is so hectic. Also I will be paying for my own pocket for these classes which is a big commitment on my part.

I dont think it will be a waste as its a investment in my carrer which will pay off .
