I Faced Several Rejections Along With Other Challenges In My Pursuit Of Admission.

In 2017/2018, while finishing my final year at the University of Porth Hacourt, Rivers State, I started thinking about further studies. I knew I wanted more, but there were major obstacles, especially the lack of funds and the knowledge gap I had to bridge. I didn’t have the resources to continue my education, so I had to figure something out. During my service year, I focused on learning about scholarships and the application process. I also began preparing for standardized tests, knowing many schools required them. But with limited funds, I had to reach out for help, and thankfully, I received it. Through my research, I learned from EducationUSA that taking these exams could make a significant difference in getting accepted. I also worked hard on my Statement of Purpose, revising it multiple times and asking others for feedback to ensure it was as strong as possible.

Despite the careful preparation, the journey wasn’t easy. I applied to seven schools, five PhD programs, and two Master’s programs. The schools I applied to for PhD were the University of Oklahoma, University of Alabama, Reseda Botanic Institute, Stevens Institute of Technology, and Kent State University. For Master’s, I applied to the University of South Alabama and Kent State University. Out of the seven, I received four offers and three rejections. I chose the University of Oklahoma because it offered a fully funded PhD program, which was a huge deciding factor.

Through all of this, I learned a valuable lesson: rejection is part of the process. It’s easy to question your worth, but those rejections don’t define you. I had been rejected many times before, including in my first attempt at applying to the UK. In the end, I was fortunate to get a full ride, which made everything easier, including skipping the typical tuition deposit. Looking back, it wasn’t a smooth journey, but every challenge, every rejection, and every setback led me to where I am today.

Life After Gaining Admission

After I gained admission, I realized that the journey ahead was not going to be easy. Everyone says a PhD is tough, and that’s something I soon discovered firsthand.As a graduate assistant, it’s even more demanding. However, beyond the academic work, there were so many other aspects that made this experience both overwhelming and rewarding. One of the most important lessons I learned early on was the significance of my relationship with my PhD adviser. It’s like choosing a life partner, you need someone you can work with, someone who understands your strengths and can support you when things get tough. This made a huge difference for me. I also had to ensure that what I was working on aligned with both my skills and future goals. When it comes to studying, it’s not just about choosing something popular; it needs to have long-term relevance.

Furthermore, the workload was no joke either. You’ll find yourself juggling between research, teaching, grading, and attending classes, but setting clear goals and breaking things down into manageable steps has helped me stay on track.

What really surprised me, though, was how much trust professors had in me. The open communication and responsibility I was given early on felt comforting, and it boosted my confidence. Despite the challenges, this journey has been incredibly fulfilling, and I’m growing more with each step. Two years ago, I won a departmental scholarship and last year. I won another one. This further boosted my confidence and made me realize I was capable of doing so much more.

Lessons from My Visa Interview Process

Navigating the visa interview process can be tedious, but at the end of the day, it’s worth it if you’re successful. I had my visa interview at the U.S. Consulate in Lagos, Nigeria. I remember walking into the consulate, only to see the person ahead of me get denied. I couldn’t help but wonder why he was rejected, and as I approached the same officer, I felt a wave of uncertainty come over me, but thankfully, my visa was approved. 

The visa interview is like an exam in itself, and one thing I quickly learned was that preparation was key. It’s not just about having the funds or the right documents; it’s about presenting yourself with clarity and confidence. I engaged in mock interviews with two different people, practicing for hours, refining my answers to common questions, and ensuring I could speak logically and coherently without stuttering or stammering which will make me appear unsure. Before that, I researched possible questions online, prepared responses, and ensured that I understood how to communicate my story without over-explaining or under-explaining.

As I walked in for my interview, I took a deep breath and reminded myself of the importance of composure. “Your composure is very important,” I recalled from my preparation. This was a crucial tip. I also understood the value of asking for clarity if I didn’t fully understand something. I didn’t want to answer a question incorrectly because I misheard or misunderstood. “If you don’t understand something, ask for clarity before answering,” was another piece of advice I had taken to heart.

I walked away from that experience not just with a visa but with a deeper understanding of how preparation, focus, and composure can make all the difference in the face of uncertainty.

I Learnt The Importance Of Adapting To And Cultivating Balance

When I first arrived at school, I assumed my life would revolve around academics, but I soon discovered the importance of finding a balance. The constant pressure of coursework and exams could easily take a toll on your mental and emotional well-being if you don’t learn to step back and recharge.

For me, that balance came in the form of hobbies. I also play the piano, and it helps me reset and keep my mind fresh. Soccer is another sports I engage in and it helps me connect with others outside of class. It became a tradition to meet up with friends, even if it was just for a casual match. While my academics were always at the forefront, these activities were essential for maintaining my overall health and well-being.

I also made time to visit the gym whenever possible, and so far, it has helped me manage stress and stay physically fit. These moments of self-care allows me return to my studies with a clearer head and more energy.

What I’ve learned is that while your studies are incredibly important, your mental health and personal well-being should never be neglected. Finding hobbies that help you unwind, whether it’s sports, music, or any other interest, isn’t just about having fun. It’s about maintaining a balanced life that allows you to thrive in all areas. 

The African Potential And Opportunities

One of the most valuable lessons I’ve learned during my studies journey abroad is that you never truly know how much you are capable of until you are placed in a situation that demands you to rise to the occasion. Coming from a background where I may have doubted my potential, I’ve realized that within every one of us lies untapped potential waiting to be harnessed. Whether it’s overcoming academic challenges or achieving accomplishments like departmental scholarships, I’ve discovered that there is much more I can do than I initially thought. The potential we have is not dictated by our past or present circumstances but by the will to push forward, set goals, and pursue them relentlessly. This realization has inspired me to not only believe in myself but also to inspire others to do the same.

Looking towards the future, I’m excited to apply the knowledge and skills I’ve gained. One of my major goals is to work in a research institute focused on quantum science. I believe there’s a huge opportunity for Africans to be at the forefront of this emerging field. Through interdisciplinary research, I hope to contribute to advancements that will impact both the global and African scientific landscape.

Moreover, my experiences abroad have reshaped how I view Africa. I now see the continent not as a place limited by its challenges but as a gold mine of untapped potential. Africa has the largest young population in the world, and that demographic represents a unique opportunity for growth and innovation. My time in the U.S. has shown me the possibilities for what we can achieve, and I’m determined to bring back the knowledge and insights I’ve gained to help move Africa forward. Africa has a bright future, and through education, research, and dedication, I’m confident that we can overcome the barriers we face.

In conclusion, studying abroad has not only been a journey of academic growth but also a deep personal realization of the power we hold within ourselves. Africa’s potential to lead on the global stage is immense, and with determination, we can shift the narrative from limitations to limitless possibilities.
