To get good marks in math examinations everyone needs to practice but I can not carry a pen, paper and a math book with me for the entire day and because of this

I had decided to use a method in which I will try to recall information from **two** different text books in my own words by using **two** different Memory Palaces simultaneously(And each memory palace will contain the information of only one book)

And with each paragraph of information that I will recall in my own words I will make an educated guess of the position of equivalent text in my textbook(which will be done for both the memory palaces) to get two numbers which will be joined together to form a two digit number(in the minimum),

In this method the sums which will contain the numbers will be the the **type** of questions in which I have difficulty(And the difficulty of every question will be decided by the recall of paragraphs from both the Mind Palaces),

And my question is that **"Can using this method continuously in my mind improve my accuracy in Maths and will practicing Maths using this method improve my accuracy in Math examinations which are written?"**

I doubt that the method above is original and there is another method with which I find similarities with this method and because of this I am taking little credit for this method.

And,

Cheers.
