Flashcard for writing TOEFL iBT

Here is how I create flashcard to practice speaking:

I use an Excel sheet, I divide the sheet into cells. I write a topic in each cell. For example:

My cells have the dimensions 4 x 5 cm. I print several cells into an A4 paper, and then I cut each cell. I use a good and thick paper so the card will not be damaged. I punch a hole on the cells and put them together by a cold ring. On each cell, I write some key words of the answer to help me practice. Example, with the topic No 2 above, I write at the back of the card: agree, reason: learn a lot from parents; parents always available for any questions and help.

I can put these small cards in pockets so I can carry them anywhere. When I have a free time, I take them out and think about three ideas to write. Doing this way, I can practice to think very quickly.
