Abundant information but needs update
Format: Kindle
I struggled a little when try to decide how many star to give. It's an excellent book and very informative. It feels like I was not reading a college admission advisory book, which very often are dry and mechanical. It feels like reading stories of students and AOs, I got attached and involved emotionally, and really felt for them. But there were abundant information in the book, I was able to use the book to answer most my questions. If you need a list of YESs, Nos, Warnings..., then this is not the book for you. If you need to know what happens during admission process, then this is an excellent book for you. Based on the information in this book, I was able to extract my own conclusions. The reason I hesitated if I should rate this book as a five stars book is how long ago it was written. A lot has changed. Many aspects stayed same, but many aspects changed. It will be misleading if this is the only guide book you are using. Wish everyone a great college application season.

An intimidating read
Format: Paperback
This is a scary book to read if you are anyone, but most especially a Parent of a college bound junior or senior. The writer, Jacques Steinberg, a NY Times Reporter writes beautifully and captures the college application process in an authentic way, without overdramatization. His style and sensibility reminds me of Jon Kraukeur. I was prinicipally struck by the heroic Sisyphean efforts of the admissions office and the immense gap between public school and private school admissions counseling at the high school level, a gap which is even greater today. This is also a very good description of Wesleyan University -- what it is not so good at, and this is no fault of the author who tries to make this point and the related one that follows , but the best approach for the applicant is to find a college where he and she can thrive and trust the process, the admissions folks are very dedicated to bringing in students who can add value and to whom they can add value -- more to the point when a good fit is made, all the effort and anxiety is well worthwhile to the school and the applicant. good luck and best wishes to all of you who are college bound.

A must read for anyone getting ready for college!
Format: Kindle
Very eye opening! I really got a feel for what the admissions officers go through. I really had no idea, i thought it was much more impersonal. My only complaint is that I wish along with the other students in which they chose to go into depth that they would have chosen an international student. I would have liked to have known how they were evaluated as compared to the American applicants. But still this book was not only helpful but interesting as a novel with personal stories you were interested in following.

Illuminating insights on the transformative power of college
Format: Hardcover
Mindset Matters is an inspiring, timely, and useful exploration of how higher education can transform lives by fostering the key mindsets essential for success in today’s complex and fast-changing world. Drawing on his extensive experience as a leader in higher education and lifelong learning, Porterfield makes a compelling case for cultivating five critical mindsets — Discovery, Creation, Mentorship, Collaboration, and Striving — all aligned with a growth mindset. He explains how colleges can develop these mindsets to prepare students for lifelong growth. The book is grounded in real stories of students whose lives were transformed by higher education. The thoughtful narratives illustrate how institutions can create environments and systems where all students can thrive. Through this work, Porterfield offers a roadmap for helping prepare individuals to embrace growth, pursue opportunities, navigate challenges, and drive meaningful impact — throughout their lives. Whether you're an educator, a parent, or someone interested in the future of higher education, Mindset Matters will leave you inspired and equipped with new perspectives and strategies. I highly recommend it.

Disappointing
Format: Hardcover
I had high hopes. But this book seems to be more of a rosy retrospective of one college president years in charge than it is a real useful book about how to help students.
