I missed my early morning Quran class for three days in a row, and I was much worried. Also I was having difficulty memorizing, may be because the verses are a bit complicated to learn, like the verses about divorce and other social guidlines.
But anyway i recited the new verses for my teacher and she actually made memorize the next ones right there in a few minutes. We did the translation, and thats ofcourse the tip, I dont think I could do it if i didnt know the meaning of what I memorizing.
The verses are long, starting from 232 onwards, so she made me do them in very small portions. And then reading the whole verse, and in the end reading the whole Ruku (section) together. I read behind her two or three times and it didnt take more than 25 minutes till I had it done. Alhamdulilah.
So the tip is, (for us non-arabs) to learn the meaning of each word before we start.
And then keeping the meanings in mind, doing it in small portions, and finally doing it as a whole.
