Logistic Regression

i’m doing logistic regression and can’t get past 79.4 score using realstats resource package for excel (as i can not do logistic regression using excel’s native functions because i’m a noob). i used pclass, title, gender, fare, embarked , below18, age, sibsp , parch, and titlesurv, and used .6 as my cut off point. is there anyone here who was able to break .8 mark using just logistic regression?
