The JLPT exam is made of 4 levels where the 1st is the hardest (near native level) and 4 is the easiest. then second hardest is 3rd level etc...i think you should wait atleast till you've studied it for a year. do you study japanese on your own? if you do, the best thing to do is get a teacher (ONLY NATIVE JAPANESE) i know from experience, non native japanese teachers are not the same no matter how well they know the language. i took level 4 after 2 years of studying japanese. and i did JLPT again last year and passed level 3, but i've studied japanese for almost 4 years now.
good luck
