I wonder if someone can help me.

Does anyone have any good studying hacks? I have two IT self-study certifications that I need to study for and pass within the next three months and need some help.

I've dedicated a lot of time and effort into techniques such as MindMapping - even paid the money and bought the software. I find that I need to go away and learn this before I could even start learning the subject material that I need to. This sets me back even more. I don't have a problem devoting the time if its really worth it.

Before I spend even more time learning Mindmapping I wondered if I could be looking at some other more useful, quicker to learn techniques. Or even just some reassurance that I'm following the right path.

TIA

Jason
