I just started the RN-BSN program in August of this year and was majorly stressing the biochem. I appealed the class before starting because I had read that previous chemistry classes counted for biochem. That is no longer the case. Biochem is required. To be brave and get biochem out of the way I selected it as my first class. It took me two weeks. I'm not going to say it was easy because you really do need to understand the material for the tasks, but it is completely doable! Two weeks means a lot of full days making models and drawing diagrams, and a lot of nights staying up late watching the Thinkwell lectures and working on PowerPoints, but it was well worth it. It was a great intro to competency-based learning and I challenged myself right from the start. Don't sweat the biochem, really. The great thing is there's no "test". Competence is demonstrated by finishing the tasks. It really isn't as horrible as many (myself included) think it is.
