Unfortunat­ely­ I think a lot of lltite white lies/gener­alizations­ must be told in introducto­ry­ coursework to make the material manageable­,­ so tests have to take these lltite white lies into account. Think of the test as just a challenge for your problem-so­lving­ abilities- figure out what they want you to say based on what you’ve been told, even if you know slightly better based on your extracurri­cular­ reading. Just try to be aware of the lltite testing tricks, and simplify your answers if you need to. But even if your scores do suffer a bit on tests right now, you’re eventually going to have an advantage when you get to higher level coursework and especially if you go on to graduate work. I’m not a science teacher, so this is just an opinion… maybe some teachers might have something to say?(2) I love the Clayden text as well. I think they actually do introduce some organometa­llic­ topics fairly well. The only dedicated organometa­llics­ text I’ve used is by Crabtree (The Organometa­llic­ Chemistry of the Transition Metals), and I would recommend it. I’ve heard the new one by Hartwig (Organotra­nsition­ Metal Chemistry) is good as well, but that’s a much heftier book.(3) You didn’t ask me about this, but I really like Grossman’s The Art of Writing Reasonable Organic Reaction Mechanisms­.­ If you like organic chemistry. It’s pretty small for a textbook, and it’s more the kind of book you can read start to finish, with bits of humor woven in.Best of luck to you!
