yeah I have those and the physical flash cards. My problem is not sitting down and memorizing enough. I have been winging it.
Then stop winging it! I'm in Hebrew and we're at about ~200 words. Believe me things go so much better when you know the vocab. Then all you have to worry about is figuring out what the sentence says instead of what each word means.
My routine is to sit in the restroom at work for however long it takes to memorize the 10 vocab words and how to spell the root. Some days it takes 15 minutes and others it takes 45.
In my limited experience with the languages, half a semester of Greek and almost done with my first semester of Hebrew, memorizing the vocab and reading outloud a lot are key.
Memorize, read, rest, memorize, read, rest, memorize, read, rest...rinse and repeat.
