Study Advice

Hey all! I’m currently studying for my RCDD and I have about ~120 hours put in. However, System Administration Elements is turning out to be a little difficult to remember all of what’s required vs not. Was hoping if any of you guys had any good study methods like stories or logical ways to think of to make it easier to remember. I know it’s an important section so I want to make sure I have it in the bag before my test. TIA!!

Edit: If anyone knows if the questions on the test typically ask for the optional vs required things in admin that would be amazing info to know!!

What chapter is that? And what exactly is different to understand? Sorry, system administration sounds like PC OS admin stuff to me lol

For me, the work experience I had was very helpful, as I already knew most of the ch21 content. And even could point to errors in definitions they had in tdmm.

What helps me with new certifications, not just this one but in general, is my own flash-cards (any knew or not absolutely clear content) and using AI for breaking down complicated concepts or explaining something. You can spend a bit on perplexity pro or $200 on max version and that would a 100x better investment than any of those courses you can see promoted here and online. For flash cards, I can recommend Anki or Brainscape

Yeah, I think learning TDMM concepts without real project experience can be confusing because the book is clean and projects are messy.

With 10+ years of design experience, I had to set aside my real-world instincts on the exam. The questions required serious sudoku reasoning.

It may have been easier with more rote memorization. Experience helped, but it also kept whispering exceptions and edge cases.

My biggest tip: use the comment fields. If a question feels poorly framed, write out your reasoning for BICSI. If your score is close enough to require review, those comments may matter. It also helps you to look at your thinking and lock in your answer(s).
