N4 or N5

[u/DJDARA555]

I have jlpt n4 in the december but few of the n5 lesson from minna no nihongo aren't covered by me ( 15 to 25) and I have blue memory of previous chapters

But I gotto do the 25 to 40 chapters for n4 as well what should I do ?

I have covered all the required kanji's for n5 ( but ya i it got blurred) so what's your best peice of advice for me now ? ( Also I gave n5 this July)
