hi, so ive just started doing my a levels at sixth form college, one of which is biology. im vegetarian and believe strongly in not using animals for human benefit. my teacher said that next week we will be dissecting sheeps hearts, and i really really dont want to do it. i am also prone to feeling faint when i see really gory things anyway. can i opt out of doing the practicals? i would be happy to participate in any involving plants / humans i just dont want to do any with animals. at my old school this was never a problem, i was allowed to just watch a video or complete a worksheet instead while everyone else did the practical, but as its a new school im not sure if its allowed. im doing the SNAB biology course if that makes any difference. has anyone else been able to not participate in bio practicals in the past? thank you!
