How can I improve my score upto 320?

Today, I took my powerprep 1 test. I got 148 in Verbal and 163 in quant. Though I got to correct 35 questions in Quant. In verbal, I got almost 6 SE correct out of 8 and 4-5 TC correct and remaining I corrected in RC. My exam on 13th October. So, what should I do right now. I need 155 in Verbal and 165+ in Quant. Is it possible within this time period?
