What a Great Ride
Format: Kindle
This book was a fun ride from start to finish. While not fully LitRPG, but sorta' LitRPG light based on the system that's set up, the world building makes sense and fits the story very well.
The real shining star was the character development. I felt like I knew the characters after a few lines and as the story developed, casual comments helped build a deeper web of interrelationships.
Also loved the blurbs at the start of the chapters - thought they really added to the world building and backstory in a fun way.
Can't wait to read more about Cat!

Wonderful
Format: Kindle
This was everything I was hoping for and more. Great world building, awesome characters and a mythology that just left you wanting more. Little snippets at the start of each chapter that hints at the history of the world at large while also slightly framing the content of that chapter? Spot on. My one issue, and I believe others have pointed it out, is the fact that the text is grey and not white, which can make it harder to read when you’re, say, outside. But that’s a formatting thing and has no bearing on the contents. I’ll be waiting in line to get the sequel as soon as it appears! Oh, since Amazon can be iffy about it, the LGBTQ+ tag is accurate!

I love this author's storytelling!
Format: Kindle
This is my fourth series by Ravensdagger, and I am truly addicted to the masterful storytelling. This series is just as entertaining and full of elaborate world and character building as I have come to expect. That said, I docked a star for the first time ever with this author because this is the first of the author's series I have experienced that contains the rampant and horrifyingly overused profanity of so many authors in this genre. Honestly, it was so disappointing and so prolific in this book that if it hadn't been just an awesome story full of so much depth and entertainment, I would have docked one or two more stars. We simply don't need those virus words constantly infecting, narrowing, and eventually taking over our much broader vocabularies as they do so very often. But the fact that I left 4 stars really does speak to how much I enjoyed the book other than that. I can't wait to start the next one, and I hope it will be as refreshingly free of profanities as this rest of this Ravensdagger's excellent body of work.

A Must-Read for College (and Even High School) Students
Format: Paperback
First of all, this book really cuts to the point. If you are skilled with skim-reading, you can get this book in about 2 1/2 to 3 hours.
Second, while these strategies are currently untested by me, they seem really practical. Rather than saying "study" or "write paper" or "take test", Dr. Newport lays down specific, useable guidelines for all areas that are intended to cut down on time spent on schoolwork. This helps you with more time to have fun, do extracurricular activities, or work 60 hours a week (like I will soon be doing).
Third, this is THE anti-procrastination book, although I don't get the concept of starting term papers a month before they're due as the examples did. The whole concept behind this book is making sure you've got as little work going as possible that takes as little time as possible. Doing things upfront will ease your load later when the assignments and papers start rolling in and out.
There are only a couple of issues I have with the book.
1) Dr. Newport almost makes the use of personal laptops compulsory in college. I get why it would be such an asset, but for some of us it is more of a liability than an asset. I really believe one can get through college without a laptop at a much smaller personal expense than the costs of buying a laptop/accessories, printer, ink, etc. If you already bought one, that's one thing, but if you haven't, why do you need one? Just use pen/paper and the computer labs' computers and printers. With the printers, odds are you're paying the same amount for 1000 pages that you would for toner (paper is free with the way they price it), and you don't have to drop the cost upfront, but pay as you need the printer. Financially, you're better off skipping the personal printer.
2) He didn't discuss what format to purchase textbooks, but considering he was so insistent on portability, I would probably haphazard a guess that a hard copy is the only way to go. Sure it may be expensive, but what if your Kindle or iPad gets stolen?
Overall, highly, highly recommended. Get this for your child as an early (or very early) graduation present. Teaching them these things will save them a lot of headaches later on.
One last note: This book is not for the lazy. If you aren't willing to do the work, don't expect this book to help. However, if you're someone like me who's sick of lazy and wants to convert, this book IS for you!

One more crappy college study guide
Format: Paperback
When I was taking 4 classes at my local community college, I tried to follow the part of the book that said just to learn math by examples. I ended having to drop the class because at first I was actually ahead of the professor. Then I tried this stupid book's technique of learning by examples and I ended up falling behind. The same can be said of "What smart students know" it's actually a good technique (smart students), but you end up spending hours thinking up questions. Questions can be a part of the process, but it can't be the whole process. I just bought an online course than is way better than both of these combined. It's so good. The point I'm at in the course you can memorize up to 50 items in reverse and forward. You can also tell which place in the list. An example could be
The order of my hallway:
Dog = front door
Cat = wall
Duck = light switch
Printer = holder
Hitler = chair
MAO = rug
Goku = ceiling light
Kurrin = mirror
Gohan = heater
Frieza = painting
You would then connect / visualize each word / picture with a part of your house. The rule is to visualize each for only 6 seconds while recalling can only take 6 seconds. If you miss one you have to do the six second process again until you make no mistakes.
P.S. I'm not telling anyone the name of the course or where to buy it. I want to be ahead of all other students.
Edit: I'm back in college taking two college level courses. While I don't agree with everything in this book (I have to re-read it) I agree with 80-85% of the methods used in this book that I remember. Such as not doing the reading he was right. I haven't done the reading in my psychology 101 class and have only focused on taking / memorizing / learning the notes and while I haven't gotten a grade yet, I actually feel I'm learning enough and today in class I note notes from a documentary we watched. The professor said to do the reading for chapter 2 of the textbook. I'm not even going to do it. I'm going to just take notes in class then go over the reading. I did this for my 1st set of notes and I didn't understand something in the lecture notes. I ended up re-reading that / part / example [it was on the scientific method].
I remember from taking my developmental math class that the professor was actually doing examples (even though I couldn't figure out from what part of the book they were from and / or I couldn't write every example like he said) If I had just asked questions and either watched videos on Youtube I would've probably remembered the material from that class.
I'll do another edit once I'm done with classes. I'm also going to write / provide a list of books that I think are good for learning and have good advice for college.
Edit: I ended up trying to do the advice from this book and if I didn't look up the answers for the test for my psychology class I wouldn't be in college today. I'm not saying that all of this book is bad but I went from thinking that 85% of it is good to now thinking that 50% of this book is good. The other half is crap. Such as the technique for Q/E/C he doesn't give any examples or enough examples. The other advice like making your own problem sets I wouldn't have thought of. Even though this is an all right technique your wasting time because you can just practice doing other peoples problems (like those online or from a professor) or do Bullet point concept from another book I read (I'm going to provide a list once I'm done with this review). The one technique that is very good is the lecture technique he mentions in the book. For some reason, this technique helps with putting material into memory. His section on writing papers is also very good. His explanation on how to prepare for and take exams is also good. Also, he should have made the book more visual and put actual writing from actual students other than that it's an all right book.
Here's the list of books I've read (so far) that will most likely get you A's
College Rules
https://www.amazon.com/College-Rules-4th-Survive-Succeed/dp/1607748525/ref=sr_1_1?s=books&ie=UTF8&qid=1530133408&sr=1-1&keywords=college+rules
Guaranteed 4.0
https://www.amazon.com/Guaranteed-Follow-3-Step-Plan-Dont/dp/0974264806/ref=sr_1_1?s=books&ie=UTF8&qid=1530134451&sr=1-1&keywords=guranteed+4.0
How to study in college
https://www.amazon.com/How-Study-College-Walter-Pauk/dp/1133960782/ref=sr_1_4?s=books&ie=UTF8&qid=1530134633&sr=1-4&keywords=how+to+study+in+college
The only book I've read from cover to cover is GT 4.0 it's probably the best in my opinion because the system in this book will get you A's. The only reason last semester I didn't get A's was because I didn't follow the system to the t. If you follow the GT 4.0 system to a t and don't get all A's she'll give you $100.
Hope this helps.
Edit 2020:
From what I remember reading this book, this applies to college level courses and even at the same time I tried using his question / evidence technique while taking a psy101 class and couldn't do it. Also he's right to a very large degree about living off of lecture notes. Living off of the lecture notes IMHO can only be done if it's a science science class or a college level math class. I'm currently taking a pre-req class and the professor explains everything. Along with the Guaranteed 4.0 technique this is a pretty decent book.
