Marinela Slavcheva

I provide personalized tutoring in both Biology and Korean language, tailored to individual student goals and learning styles. My teaching is focused on building confidence, developing deep conceptual understanding, and supporting long-term academic success.

In Biology, I work with high school students to prepare them for:

• The national matriculation exam in Biology
• University entrance exams for Medicine and Pharmacy at the Medical University
• Ongoing schoolwork, project support, and foundational understanding across biology topics

In Korean, I teach students of various levels and backgrounds, including:

• High school students preparing for the TOPIK exam
• Learners from specialized language schools such as 18th and 138th high schools in Sofia
• Adults and enthusiasts interested in Korean language and culture

My teaching approach is student-centered and results-driven. I emphasize:

• Strong communication and trust, allowing students to express difficulties without fear
• Custom learning strategies based on each student’s strengths and needs
• Visuals, analogies, and active engagement to make complex topics accessible and memorable
• Encouragement, consistency, and clear structure that lead to measurable progress

I have a proven track record of helping students who have struggled with traditional methods—supporting them in finding new ways to learn, regain confidence, and achieve their academic goals.
