Kaplan's test for IBT

I had taken paper based toefl before, from which I got an excellenct score. But unforturnately, it expired. So I had to retake IBT.

I used Kaplan to practise yesterday, however only got 67% and 60% accuracy rate for reading and listening section. What a shame! Anyone has similar experience to share with? How to improve? 

Do not so care about the accuracy rate of Kaplan because the perspective of the questions between Kaplan and ETS is totally different. I even got the low rate for Kaplan reading section, but in the really test it is much better. You can use ETS practice test to evaluate your level, which would be closer to the really exam. Good luck!
