Supposely, your real MCAT is a bit higher than Kaplan. At least that's what they claim at Kaplan. From my personal experience (and I took Kaplan twice -second round for free though) my actual MCAT was lower than my Kaplan scores. Especially writing. However, some of my classmates who didn't mind sharing their scores said it was about the same. That's my 2 cents.
I never got above 32 on my Kaplan exams. My real score turned out to be 36.
Kaplan really helped me with WS btw. Just pay attention to what they say. Make sure it's 3 paragraphs, each paragraph addresses given question, use an example in each paragraph, avoid controvercial examples, etc. I am a lousy writer, but was able to get a 'Q'.
For the rest, it's studying the material and practice, practice, practice.
I SCORING 30-32 ON THE KAPLAN TEST. IT WAS PRETTY ACCURATE ON THE SCIENCES HOWEVER ON THE ACTUAL MCAT I GOT 27, MY VERBAL WAS A 7. THIS WAS A SHOCK CONSIDERING THAT I DIDN'T DO MUCH B/C MY KAPLAN VERBAL WAS IMPROVING THROUGH THE COURSE AND WAS AT A 10 AT THE END.
MY AAMC PRACTICE TEST SCORES WERE EVEN MORE OFF. I GOT 11,12, 9 IN PS AND 12,12,12 IN BS ON TEST AAMC#3,5,6 RESPECTIVELY. ON THE ACTUAL I GOT ONLY 10'S. MY STUDY BUDDIES HAD SIMILAR DEPRECIATIONS.
I AM TRYING THIS THING AGAIN, SO ANY ADVICE ON VERBAL WILL BE ACCEPTED IN OPEN ARMS. I AM TRYING EK FOR VERBAL AND GOING TO DO PRACTICE PASSAGES EVERYDAY UNTIL THE REAL THING.
