I started preparing for the exam 2 months ago but not very intensively - my preparation plan was to work on 2 to 4 chapters of E20-065 course book a week. I also used 'web-based references' but there were no exercises there. 1 month before the actual exam, I have taken access to practice test at for Dell EMC E20-065. I took 12 tests in total and they proved to be very helpful. The exam questions were similar although please beware of the small differences that might be misleading. If you are not sure about the answer please take your time to think how Dell EMC software operates and what the values are at compilation phase. It is very important to understand the mechanics in order to pass the test. 
This practice test helped me a lot to achieve a dream score. Recommended to all.
Good luck to you all!
