For SC, the book people recommend most is the MGMAT SC
For DS, you need to have a strong overview of quant. Remember, for DS the answer options need to be able to answer yes or no. If you can say with certainty the answer option is "no", then it is sufficent.
For RC, there are a number of things that work for people. Consult the debriefs and the verbal book thread to resolve your weakness.
