Reply to Beatmatching Tips

I'm following ellaskins on youtube to try and learn how to beatmatch, but I'm having trouble isolating the two different tempos.

Say Track A is my current song and Track B is what I'm mixing in.

1. Cue B
2. Get Track A tempo in my head
3. Exaggerate Track B tempo and slowly bring it down

The problem I have now is that I'm getting confused when I try to determine if the tempo is too fast or too slow.

Are there any tips on how I can do this? Boost the bass EQ? Or is this just something that will take time?

Thanks!
