Since you started your job, how many programming books have you read to get ahead in your job?

Examples:
- You're a Java programmer, so you read the OCP for Java 11 and then you get your OCP cert
- You're a .NET consultant, so you read another .NET book

Hi guys! I got an opportunity in one of the biggest consulting/strategy companies in the world, however I need to write the OCA and OCP Java exams to get in. The OCA is in about a month + 2-3 weeks and OCP towards the end of the year. I kinda know Java but the exams seem to be hard. May you please guide/advise on how I can get over this mountain :)? Anything that worked for you? Or did not work?

My goals this year:
1. Getting certified for Spring core
2. Getting certified for Java OCP 8
3. Write my first blog about “something interesting”
4. Update my personal website
5. Getting a drivers license

So if someone has some ideas/tips that would be great.
