if you want to pass 300-115, buy you a premium month of this :
I usually buy just one month and pass the exam after this. Good community too in the "Share your TSHOOT v2.0 Experience "
it's always up to date and I passed all my CCNP exams on this site. Now I'm due to renew my CCNP before February and I'll do the TSHOOT exam again using this site.
Too bad they don't have CCNP DC too
You will encounter :
12 lab-sim (no configuration change, only answer several questions doing ping and show commands).
and about 17 multi choice and drag and drop.
Honestly, it's probably the most fun exam of all cisco exam and very easy with this site.
