I could use some Mandarin Chinese help...?

Hello, I am finding it difficult to remember the tones for all the words I am learning. I understand the concept of tones and how to use them just fine, I just can't remember the tones of the specific words. For example, in a simple sentence like, "Dui bu qi, ce suo zai na li?" I find it a bit hard to remember that it's "Dui4 bu4 qi3, etc,,," Other than straight up memorization and repetition, does anyone know of handy tips for this?
