yup, thats my plan. Its one of the long questions that comes up, the questions where you CHOOSE which one you want, and I'm gonna do the questions that aren't genetics. It might turn up for a few short questions though, thats the only downside.
keep in mind you will have no choice on the exam then, you know its going to come up, usually along with dna synthesis. if you just do every past question you will be fine they know its the worst answered q so its never tooo hard
