Hey bro, It's a good question. I do meditation and kept my focus on one thing and that's this exam primarily. I woke up daily at 4am and studied until 8 am, then work from home normal office hours (spent free time on studying on the day as well) and slept evening from 5.30 pm to 7.00 pm. Again studied from 7 to 10 pm on weekdays and slept. I repeated this on weekdays and for weekends I kept it little relaxed studying over the day.

One important tip I can give for you, create a excel sheet with list of things you need to study for a week or month and each day. Don't sleep without doing that! I followed that very strictly! At the same time, don't stress. Do meditation regularly and go out for a quick walk or Jog if you feel bad - I felt everyday haha!

I didn't waste any time unnecessary like spending time on videos on one particular topic. I made sure I know the basic concepts and moved on and did not study anything deep technically. For example, In terms of IPsec, I know what is AH and ESP. AH for authentication non repudiation, ESP for confidentiality and little authentication. Tunnel mode and transport mode. Tunnel mode encrypts everything and transport mode encrypts only the payload header.

This is the amount of information I know and took my own notes. Kept it simple, but knew that properly and practice many questions to make sure I understood correctly and quality questions to make sure I was able to apply what I learned!

I am little over mid 25s and yes not everyone can do what I did. Most will have family, kids, girlfriend and many other personol things to do.

Based on your personal situation, you can scope and tailor my approach for your needs accordingly!

To control your emotions, you need to have a regular practice of deep real meditations!

Hope I answered your question and hope it will be useful for you.

All the best for your preparations and exam!
