Twoside option for exam class

I wrote an entire book, 700 pages long, which contains 1000 math questions solved. When I started the book, however, I had no idea what each document class meant. I recently tried to put the book with the twoside option and it didn’t work, searching in the forums I saw that this option doesn’t exist for the exam. I tried to, but I can’t create a resolution environment similar to the one provided by the exam class, with the solution box just below the question. I am sending an image as an example. I need help with: either finding a way to put the exam as twoside, or taking everything to the book and creating a resolution environment similar to the one provided by the exam. I tried some alternatives like the exsol package, and the probsol, but I found the documentation presented quite complex and did not understand what should be done… I know how to place the enumerations of the pages alternating in the exam, but the pages do not shift so that it is in print format.
