i know what you mean about the practicals. i dont have that problem with histo practicals, but i did with gross practicals at first. it kind of sucks that you use a scope for them, especially if youre not used to using one all the time. our practicals are on a computer screen and we get to see several levelsof magnification. we are told to ID tissue, cell, structure, etc. iin terms of your vision, if you feel it might be an issue, definitely get it checked. ive done really well on my histo practicals, and my study method was watching a review video make by my professor where he went over each system and structure. he would point to a structure and say waht it was, and why it wasnt something else. that worked really well for me bc when i got to a practical, i would use a few key details to decide what something was. like an easy example, differentiating between parotid gland and pancreas via islets of langerhans. my suggestion to you would be to practice using the microscope more, so identifying things become in that situation becomes more second nature. just do the best you can. i also used a cd called histo times which was pretty helpful, bu it sounds like you should be practicing with a scope. good luck, and if you want any specific tips on identification, pm me any time.
