What are you expecting from this review?
As a general rule, the sort of functions you describe are handled better in a relational database application than in a spreadsheet application. That means anyone who looked at it would more than likely recommend the upgrade. So in that sense, what you are asking seems more like a confirmation than an analysis.
That said, some consultants will invest a free hour or two up front with a client in order to determine the scope and complexity of the contract they would offer to do the work. On the other hand, a quick "yes or no" review is about what you could expect via a volunteer forum. And, as I suggested, the answer is almost guaranteed to be "yes, upgrade to a relational database application" anyway.
Learning tools. There are lots of YouTube videos these days. There are still many good Access books available, although the internet has really put damper on that method of providing materials.
I recommend that you download a couple of the templates in Access, those related to students and classes, and similar areas. Once you have some more specific, detailed ideas and questions, it would be more straightforward to ask specific questions about what you need to do/
