But for the non-trads with less/little science/vet med background (which is a fair number of them I believe) I stick by the advice.
To be one of a handful of people in the class that do not have as much exposure in these areas makes things extremely difficult. The pace of vet school would not be the issue if I weren't starting 10 lengths behind everyone else. A lot of ground has to be made up in a fast paced race.
So certainly, if you are a non-trad with a lot of science background, then classes may not help, but otherwise, they can make a huge difference.
SOV, if you take a look back, I hated first year, with a passion. Was very bitter about it. I have been reassured time and again that non-trads tend to do poorly at first, but thier ability to connect concepts, work with people, understand interactions and cause-effect helps as education continues. I feel that is true this year where I am connecting a lot of information and seeing some of the trad students starting to fumble. There is still a ton of memorization, but much more conceptual connections. I am told next year it will shift even more towards putting together the components, and that in clinics non-trads tend to shine. We aren't here just because we love vet medicine; generally we have decided to trade something in for this oppurtunity (another career, family leisure, lifestyle, etc.)
I'm not basing my suggestions just on my experience.... I'm also including the experience of folks who took anatomy at an undergrad level (generally human) and felt it didn't help and may have even hindered, same with histology and parasitology. In some cases, students are having to unlearn material.
I am also being considering other part of life. In taking time off at my age to return to school, I am risking my lifetime earning ability. I am taking myself out of the market for 4+ years. I have had to confront the risk this creates when my husband was laid off this year. My advice isn't just about my reaction at the moment (which was more severe than yours...look at the thread about how it is going for 2013), but my reaciton looking back, and considering the business, financial, and familial implications of the decision to delay entry and pursue additional classes.
I feel confident that in another year, you will have survived, caught up, and have found your niche. You will discover that you can memorize immense amounts of material (but it will still be harder than your younger collegues because you KNOW in practice that much of that material is referential) but that you are faster at piecing it together, at seeing the practical implications, and understanding how to communicate that information, because you have likely done this often in your previous career (even though it was a very different field.) I honestly think in another year, when you get through it, you will feel differently. You may still dislike this process (I hate vet school with an intense passion, even now) but you will find the things that work for you and you will find your skills are what others are trying to learn.
I could be wrong...and I hope we revisit the idea in another year. I would not redo first year vet school now, even if there were NO OTHER consequences (ie no lost year, no lost income, etc) and if I was promised the best fellow students ever with the greatest technology and no familial stress and had all the knowledge that I have now (IE have learned all that material once already.) I think that is the biggest reason I am not sure it matters...because given all of that, I still wouldn't do that process again. I don't know that I would want to redo second year, but if someone said I had to, I wouldn't walk out the door rather than think about it (and I would with first year.) I did feel the way you do, especially about anatomy and histology, I hope you find your feet sooner than I did; its a hard year, and I think it is harder for non-trads.
