just took my first practice exam...

i got a 497 which isn't insanely horrible i guess, but not what i am aiming for at all.

i did best on the p/s and did by far the worst in c/p, i did around the same for the cars and the b/b section

my exam is on april 25th and now i am really debating pushing it back atleast a couple weeks because i do not feel prepped at all as im aiming for something in the 510-515 range

any advice on what i should do to improve is appreciated or if i should definitely push it back
