Questões Agro is a study app that turns solving questions into an interactive process with Artificial Intelligence (AI). I originally developed it for my own civil service entrance exams (public competitive exams in Brazil), but soon realized it could help many more people.

In 2023, I took the civil service exam for Agricultural Engineer at the Empresa de Desenvolvimento Agropecuário de Sergipe (EMDAGRO – Agricultural Development Company of Sergipe), motivated by the desire to work closer to my family in Sergipe. At that time, I adopted a strategy that I consider decisive for the result I achieved: I focused almost exclusively on solving questions. About a year later, I was called to assume the position, although I decided not to take it.

Fast forward to 2025. Back into the routine of exams (Instituto Nacional do Semiárido – INSA, Brazilian Agricultural Research Corporation – EMBRAPA, National Supply Company – CONAB), I kept this central pillar — the questions — but realized I could take the method further. That’s when I decided to create an application, merging technology and education to transform my learning process. This is how Questões Agro was born.

How Questões Agro was created

Questões Agro was developed in Flutter, integrated with the OpenAI API to run generative AI models directly in the app and interact with me. The idea was simple, but powerful:

• Each solved question was recorded inside the app.
• My answers served as a “knowledge base” for OpenAI’s models, which accessed them on the backend, ensuring accurate understanding of the subject.
• The AI, already with the context of my own answers, engaged in dialogue with me about each question directly in the app.

In this way, I learned actively while writing, and then deepened my studies by revisiting the questions in the app and discussing them with the AI. It wasn’t just studying: it was like having a tutor always available, trained from reliable reasoning.

What I learned by building my own AI tutor

Questões Agro brought a unique experience by turning question-solving into an active and interactive process, supported by AI. But beyond that, it was also a great opportunity to apply:

• Active learning (learning by solving and discussing questions).
• Personalized AI training for my own needs.
• Entrepreneurship and technology, applying mobile development to my own study process, sharing question resolutions on Instagram (@QuestoesAgro) and creating a dedicated website.
• Agronomy learning focused on civil service exams.
• Opening professional opportunities through the exams I took.

But it’s important to emphasize: the app was not the only tool in my preparation. During my studies, I used several techniques I consider fundamental: the memory palace to organize content visually, producing texts and slides to practice active recall, and even simulating classes, explaining topics as if I were teaching them. Each of these strategies helped consolidate knowledge at different levels.

The app became part of this set as a strategic ally, boosting my studies with technology and enabling a unique interaction with my own answers. It was precisely this combination — discipline, varied methods, and innovation — that led me to concrete results: 5th place (for 3 positions) in the EMBRAPA exam and 10th place (for 8 positions) in the CONAB exam, with a real chance of being appointed.

Behind the scenes

Not everything was easy 🌱. Solving questions and keeping the app updated required effort. Recording each answer demanded discipline and extra time, which made me reflect: technology can enhance learning, but human effort is fundamental.

In the end…

Questões Agro was more than just an app. It was proof that it is possible to use cutting-edge technology to personalize education in a practical and accessible way.

Who knows? Maybe in the future I will officially launch Questões Agro, so that it can also help other exam candidates and agricultural professionals achieve their goals.

👉 And you, would you use an app like this in your studies?

Note: The Portal Bioinsumos refers to products registered and legislation valid only in Brazil. All content is available in Portuguese.

Sustainable agriculture has been advancing significantly, and bioinputs have emerged as essential allies in this process. To facilitate access to reliable information, I launched the Portal Bioinsumos, a website created as a reference space for biological products and inoculants.

What you’ll find on the Portal Bioinsumos

• 📖 Catalog of Biological Products: Access details on fungicides, insecticides, nematicides, and other registered products.
• 🧪 Inoculants Catalog: Find information on inoculants applied to different crops and their functionalities.
• ⚖️ Legislation on Bioinputs: Access laws, decrees, and normative instructions regulating the sector.

Why use the Portal Bioinsumos

Often, information about bioinputs is scattered across different sources. Using Embrapa’s API, the portal centralizes everything, offering simple, reliable, and free access to help farmers, researchers, and technicians stay up to date.

How to navigate the site

1. Go to the homepage of the Portal Bioinsumos.
2. Click on Catalogs in the top menu.
3. Choose between Biological Products or Inoculants.
4. Use filters to quickly find what you need.

Conclusion

The Portal Bioinsumos is more than just a catalog — it’s a tool to strengthen sustainable agriculture in Brazil.

“To be happy, it is not enough to always do what you love. But always love what you do”

In the middle of my freshman year of college I gave myself advice very similar to this one. On a piece of paper I wrote some short rules to practice in my routines and hung it on the side wall beside my bed. One of them was: “Do it with love!”.

The goal was simple, no matter what the task, it should be done with love. If it was necessary to spend time on something I didn’t want to do, that time should be spent with dedication. It was no longer permissible to simply go through a certain task with an eager desire for it to pass quickly. That meant that even if I didn’t want to do what needed to be done, I should do it with dedication, with presence.

“Man changes his life when he stops doing what he wants to do and starts doing what has to be done”

Doing what needs to be done, with love, is an exercise in humility. Doing what needs to be done, with love, is an exercise in self-responsibility. And self responsibility is putting the reins of your life in your hands, becoming a leader of yourself and stopping blaming others. This kind of attitude tells you that it’s all your responsibility, whether for success or failure.

Will you build a work team? Select those who take responsibility for their lives. Select those that even to clean the floor, do it with care.

“A warrior does not give up what he loves, he finds love in what he does”

Socrates – The Way of the Peaceful Warrior

So stop wishing for the perfect day, the dream job, and that everything works out. Stop deluding yourself with what you don’t control. Need to wash a dish? Wash with love. Need to clean private? Wash with love.

Remember, among the many definitions of love, mine today is: dedication and presence..

Perhaps one of the best ways to go to learn anything is first of all to learn to learn, or to learn tools that when applied helped you to learn something. Exercising, getting a good night’s sleep, eating well, asking questions are some of these tools. Today I’m going to talk about a technique that you can apply in many areas of learning in your life.

As an example, let’s say you have an algebra test and you have a list of subjects that will be on the test. Perfect, you already know what you need to learn. Now see what a simple and very useful technique tip I heard these days from Hypnologist Alberto Dell’isola. The goal is very simple: keep certain information. Alberto Dell’isola names her as ABC technician. Basically you:

1. First you list the subjects you want (or need) to learn about a certain subject
2. Now you rank each item on your list as A, B or C
3. For this, consider that A, you master the item, B you have a certain mastery of the item but not complete, and C you don’t know anything about the item.
4. The A’s are already dominated. So your next objective is to turn items B into A
5. Caution: Don’t pick up a C-rated item before turning the B’s into A’s

This technique you can apply to different areas of learning in your life. As Alberto said, it is common for people to think that the greatest difficulty in learning is to acquire new information, however the problem is the difficult tendency to keep new information.

Still to paraphrase Alberto, it is much more important the amount of revisions you do, than worrying about learning new things all the time.

Do you understand why your Jiu-jitsu teacher insisted that you repeat the position he taught you? Do you understand why doing math exercises makes you able to solve similar exercises?

Guys, I consider Duolingo the best app for those who are starting to learn English. But not just for starters. With some adjustments, which I will list here, and adding Google Images and Youglish to your toolbox, you will certainly enjoy your studies even more, improve your communication skills in English and also be able to apply it to other languages you are practicing.

Listen to the audios before reading the lesson phrase – In Duolingo, before reading the lesson phrase, listen to the audio without looking at the possible translation and try to understand what is being said. When reading the English sentence of the lesson, avoid also reading the Portuguese meanings that appear on the screen. It is quite possible that avoiding translation is difficult for you, however insist, try to replace the translation with the image that that phrase or word can bring to your memory. To help with this, adopt the following tip:

Focus on Meaning Using Images – Want to learn new words and phrases by reducing your tendency to translate? So replace Google Translate with Google Images and Youglish. Do so, instead of using Google Translate to get the meaning of the word, use Google Images. You can also use Youglish. Youglish is a video search tool, in which you present a word or phrase and it brings as a result a sequence of videos with the excerpts in which the word or phrase you searched for is used, including subtitles in the same language as you. did the search

Repeat aloud what you read – As you learn words and phrases, repeat to yourself or a partner what you read or hear. Practicing using your voice (and if possible also your body language) will: (I) strengthen the facial muscles, train the muscles required for pronunciation and also develop muscle memory by integrating English into the use of your body; (II) in addition, your ability to understand will improve as you listen to yourself using the words (III) and your conversation will be more fluid, as you both get used to talking and you get used to listening.

One of my favorite things to do is take notes on lessons from an area of ​​my life or a subject that I’m interested in and then apply this lesson to different everyday situations. Jiu-jitsu has been that for me, a microcosm of experiences. What follows below are three small notes I took after a class with my teacher Victor Caramujo:

Among the different tools and resources of a jiu-jitsu fighter are the set of positions and movements that he is able to perform to defend himself, gain control of the opponent and finally reach the submission.

It is important to remember that, as in life, there will always be situations where there is no practical and quick solution, and therefore adaptation will be necessary. You can think of each position as a phrase in the jiu-jitsu language. If you master the most basic, you will then be able to expand your understanding more effectively.

A position is a type of step by step, and its understanding must be accompanied by adaptation to your body. However, if your answers to problems are always pre-defined, you will never progress, you will never get out of place, because the opponent and conditions will not always be the same for each and every situation.
