Trouble identifying ideas/words with Math Strategy

Hello, I’m having a really hard time with the math strategy. I’m pretty decent at identifying whether the sentence is a contrast/support, however, I cannot for the life of me accurately identify words or ideas to fit into the blank. I’ve rewatched the early dedicated text completion videos and while they are helpful, I still find myself a bit lost whenever I attempt a new question. Are there any other resources on gregmat that I can watch to help improve my understanding of the math strategy?
