Wasting Time on Logic Games

TRAPPEDUNDERLSAT

I've noticed that a huge issue I'm having right now is drawing way too many boards on logic games. Whenever a question introduces new conditions, I can't just picture it in my head- I need to be able to visualize it. I've always been the same way with numbers, I've always been terrible at mental math. What should I be doing to help this? Will I make better inferences in time? I take the LSAT in like a month and would love to address this soon.
