No one can answer that, score can go up or it can go down, it is an adaptive test. 4 weeks does not matter, the quality of time you spend matters more than the quantity of time. Ideally assuming you are using time wisely you can lift +/-30 to 40 points across attempts that is the standard error on adaptive tests
Also, 1 practice assessment is not a big enough sample, you will need to take more attempts and once you steadily achieve that score you can confirm your ability across sections, meaning what happens if the mix of questions changes, what if you get more RCs less CR or vice versa, what if you got more arithmetic less algebra and how did your score change. All depends on individual strengths and weaknesses....
