Craftyjulz welcome! So glad you have joined us. And no worry about keeping up, take your time and work at your own pace. The clues will always be on the QB, they don't get taken down when the last clue is given.
Actually what you need right now are two groups - one a light neutral and the other would be a mix of medium to dark scraps. If you don't have a lot of neutral scraps, you can use yardage of a small to medium print, or solid, or tone on tone, or mottle. Something to contrast with your darker scraps.
Later on, you will need more darks. And that too could be yardage if you use up all your dark scraps in the clues to come.
Don't hesitate to ask any questions you have.
