That is a pretty vague question given the lack of background information, but in general finishing the section is the most critical component. So in short, you should attempt all of the questions. If you struggle a lot with timing, consider employing "wild cards." These are questions that you realize you will most likely not get and, within 30 seconds, guess and move on. This frees up time for the questions that you have a better shot at answering correctly. It is a strategy mainly designed for quant, but can work for verbal as well.
I hope this helps!!!
