Reply to manually beatmatching using a controller?

hi guys im new to djing.. and bought a controller, pioneer ddj-t1 (after being recommended by my teacher) when i started.. after learning for 3 months now.. i know the fundamental of mixing.. and kind of pissed off that he recommended me a controller..

reason is because i want to be able to manually beatmatch by ear as in cdj (as most clubs now only have cdjs).. with that in mind with my economic situation now.. i couldnt afford to buy another pair of cdjs and mixers..

is there anyway that i can practice my manual beatmatching by using a controller? if so, are the (% of bpms) in controller the same as in cdj?

for example if a song in deck a is -0.80% slower than deck b (in traktor) would this to equate the same in cdj (assuming same song)? thanks very much
