Regarding diabetes classification challenge

i am getting 79% accuracy in the challenge, used k =25 and also normalized the data set , what else i should do achieve a higher accuracy??

Hi, for getting the in the 80’s try dropping some feature columns. And try training and testing for each value of k between 10-30.

Hi, I tried this but still I am unable to get in the 80s. Help please?

can you please share your code with me.
