I took a few community college courses several years ago at the ripe old age of 43 and was terrified of walking into that first class. Then when I had to read anything in front of the class, I almost fainted. Luckily, there was an emt taking the same class. lol I told him to hang close those days.
I was convinced I'd be the oldest one in the room and that all those young whippersnappers right out of high school would still be fresh with knowledge and would leave me in the dust when it came to understanding and doing the class work. But I ended up being wrong on both counts. *Whew*
There was a gentleman in his late 60s and two other ladies in their 50s. Once we started working in groups I noticed many of the youngsters wrote in text speak and weren't nearly as intimidating as I'd imagined. lol All of the instructors I encountered were more than willing to help and accommodate any need I had. I had to take only one or two classes at a time though due to my work load and family demands at the time. Anymore than that and I wouldn't have been able to manage.
Several of the older students enjoyed forming study groups and that was super helpful, too. Everyone was super helpful except for the few who weren't taking their own stuff seriously. I didn't finish the courses all the way through to a degree, (yet, perhaps) but it was a worthy experience. Had I continued, I would have invested in a mini-recorder to help me retain the information better. My note taking skills leave a lot to be desired, not to mention the achy hands trying to write it all out.
I even managed to make straight As in the few initial courses I took, which is something my high school self never ever experienced. That was a nice pick me up to my academic spirits as my mom still reminds me that I graduated by the skin of my teeth and shares that the school offered maximum cum laude, regular cum laude, and thank you laude, and I got the latter. Gee, thanks, mom.
Make it as fun and comfortable for yourself as you can. Ask for what you need and if asked why, just say your brain is hardwired a certain way and the things you ask for help you learn, and after all, that's why you're there, to learn. You've got an amazingly strong spirit with a huge heart. People recognize that and respond in kind. You'll end up teaching them a thing or two, as well, I feel certain. :) Rock on!
