  • Why should I choose your course?
    Java and the training of IT professionals working with this language is a core specialization of CodeGym.
    Mentors, step by step, introduce students to the theoretical part of Java and interact with them in chats regularly to resolve the problems and answer the questions.
    The course contains many examples of the Java theory application. They help students consolidate the lessons learned and use this knowledge in their future projects. There are more than 1,200 tasks with automatic verification of the solution and the final project.
    Tuition can be paid monthly, which is convenient for planning your budget.

  • How are the lessons held, and how are the groups formed?
    The mentor provides you with a Zoom online conference link, you follow it, and the lesson starts. You gain theoretical knowledge during the online class. You can ask your questions in a Zoom chat. The mentor shows you how to code. You can code at the same time while listening to the mentor. The lesson is being recorded, and we upload it the next day onto YouTube. You can save the video if you wish so.
