Understanding our services and policy

Since the services provided by GUA are advisory in nature and the final decision on selection of colleges rests with the student and family, it is understood that GUA does not guarantee acceptance to any particular college. GUA’s recommendations are based on the accuracy of information provided by the student. Fees are not accepted from institutions or programs for referral or placement of a client as according to NACAC ethical guidelines. The primary obligation of GUA is the welfare of the student. Designated fees are payable whether or not the student gains acceptance to the college of choice. Extra services are provided for an additional fee or the hourly rate. If the student wishes to apply to more than 10 schools then an extra fee will also be requested. All UCAS, University of California and OUAC applications are considered as one application

Success Stories

Davide Quinto – CEO Italy, Elab Education Laboratory

We got to know Jack from UAL which is one of our university partners. After speaking with Jack, we decided that it will be very useful for our Counsellors to hear Jack’s perspective about university admissions. At Elab Education Laboratory we help students and parents to prepare, choose and apply to the most prestigious universities abroad.

It was a very good decision to hear from Jack more about ‘Professional Development’ and how the industry of university admissions is changing. We definitely had a good time and it was also a great opportunity for our Counsellors to share thoughts with someone who has been working with students and parents directly for so many years. Thank you Jack!

We have worked with Jack for a couple of years now. As we recently finished our latest “College Counselor Training Sessions”, the feedback we received was outstanding. Our High School counselors from all over LATAM love the sessions, Jack makes sure the topics are engaging and the sessions interactive. We look forward to run these sessions again next year!”

Jack, Christian and Angelica have been so helpful in my application process. They have helped with essays, application deadlines, summer program applications and so much more. I started by looking at schools all around the world. Meeting and talking with Jack and Christian on a regular basis really helped me understand where I want to study. Angelica’s help for brainstorming essays was unique and incredibly helpful. I am very grateful for their help in this process.

“Jack and Christian are professional and experienced consultants, they really helped my daughter in focusing on her potential and translating it into a successful application. They really supported her during all the application process and answered promptly to any question or doubt she had. Adding also some psychological support. In the end she received an offer from one of the best universities in the UK, so I can say she was a successful case! I highly recommend GUA!!!”

Everyone at GUA made the entire college application process much much easier for me, from deciding on what colleges to choose to writing all the essays! The feedback on all of my essays was incredibly helpful. I also felt really comfortable asking any questions I had throughout the process and always received a response right away. I had a great experience!

Southlands International School

Jack Shull is a living encyclopedia of university systems and application processes across all 5 continents. In my first year as a University Counselor, he has effectively been my mentor and given me timely and profound insights even regarding specific institutions. A particular highlight was when he assisted me in conducting individual interviews with Y13s. Jack is most definitely the ‘go-to’ for all university queries!

When the going got tough, Jack and Christian served as a beacon of light to guide me not only through the labyrinth that is the college admissions process, but life as well. Their dedication and experience was an invaluable asset in tackling admissions during a year like no other. As counselors, Jack and Christian remain steadfast in helping to improve the lives of every soul they come across.

Proud Parents

Angelica’s help and guidance was invaluable, helping our daughter with the SAT, college strategy, and applications. She made this process so much easier! Our daughter always looked happier after her lessons. We recommend her to all of our friends and look forward to working with her with our younger son.

Proud Parent

Angelica inspired my daughter so powerfully. She instilled in her the beauty of words and the power of using them to express on paper. She impressed my daughter in ways no one had before. My daughter loved talking about her after each session. She is an incredibly interesting person and not only helped my daughter with her essays, helping her eventually get accepted to her first choice school, but inspired her for a lifetime.

Mr Shull’s counseling sessions were one of the main reasons behind my success of getting into my dream university. He helped me brainstorm ideas so that I could write the perfect unique essays. He made me think in the right way. His sessions were very useful as he followed up on all my deadlines, reviewed my essays several times & we had insightful conversations about the university selection and application process. Mr Shull’s counseling is the best.

Jack is an experienced expert of college application and counselling. He not only helped me refine my personal statement and supplementary essays that are key to college application, but also recommended the programs that most suit me based on his knowledge of me. Jack also helped me prepare for the interviews by conducting mock interviews with me several times. He gave valuable feedback so that I can make further improvements but at the same time encouraged me a lot to boost my confidence.

It was very comforting to know that someone as experienced as Mr. Shull was guiding my son through the college application process. He encouraged him to get started early and gave him invaluable advice. Mr. Shull was on a college tour with him when they visited 16 different Universities and that was when he knew that he wanted to go to NYU. My son was just offered a place at NYU class of 2017 and I’m so happy that his dream came true. Thank you Mr. Shull.
