OKAY, so im taking a bio course this summer and my professor requires the 9th edition of the lab manual. I however purchased the 10th edition by mistake, and apparently from what im hearing from others the 10th edition lab manual for bio is the only one available. Im at odds here as im unsure if I purchased the wrong book or if the 10th edition is the only available option and my courses syllabus is just outdated.

I want to ask this question as I am currently debating whether or not to play guitar. It seems like a big investment for something that I may not succeed in. Obviously no one is automatically a master in their first day let alone a year but I’m absolutely terrified of being nowhere as good as I want to be after months of practice.
