Hello Jeanne Boyarsky,
Many pages

but i am sure its worth reading.
I have clear my java certification in year 2000.
In between i have tried upgrading myself while working in IT with Java8, Java 11 certification but was unsuccessful. (I have bough book and voucher but all i had wasted my money

)
Hope this time i will be successful.
I need to restart it, how much approx. time commitment and months require? (I know this question is irrelevant and depend on person and knowledge but hope i can get some further input which help and motivate me to achieve it)
Thank You
