Series Details

About

Feel free to join after start date because prior knowledge is not necessary for further lessons and activities. We will go in depth in Java from basic syntax to coding your own programs. This will cover such topics as simple as variables and if statements to harder things such as data structures like Hash Maps or real world applications such as simulations and problem solving.

Tutor Qualifications

I have taken both Computer Science 1 & 2 and APCSA at my school, which covers both Python and Java extensively in content. Additionally, I'm a part of my school's Comp Sci Club and compute in hackathons and competitive programming competitions. I also participate in USACO and have some background in Cybersecurity as well.

✋ ATTENDANCE POLICY

1. Show up to the lessons! If you're consistently missing classes, you will fall behind, and not be able to keep up with the pace of the series.

2. Although missing sessions here or there is acceptable, please make sure to message me beforehand.

3. To get the most out of the series, you need to put the work in. That means doing the practice problems assigned, asking questions for a full understanding, turning your camera on, and participating either in chat or with a microphone.

About the Tutor

I've been active on Khan Academy for about 5 years now and wanted to give back to the community. I've tutored a few of my friends and enjoy teaching and explaining subjects, but I don't want to be a teacher. I have my fair share of commitments such as school/after school activities and sports, so I may not be online as often. Some of my hobbies include computer science, where I find endless fascination in coding, problem-solving, and developing innovative solutions. I focus on competitive programming like USACO in my spare time. I play soccer as well, which has been a part of my life since I was young, and I enjoy the rush of scoring goals, the strategic maneuvering on the field, and the camaraderie with my teammates. By integrating these diverse interests, I've developed a unique perspective that combines creativity with analytical thinking, teamwork with independent problem-solving, and physical strength with mental agility. I'm always excited to take on new challenges, expand my horizons, and make a positive impact in both the digital and physical realms. I have also achieved 1580 on my October 2023 Paper SAT with a 800 Math 780 RW Split. Feel free to message me anytime if you need help or have questions.
