Has the second training institution been giving face-to-face lectures, because most people who want to participate in IT training are based on 0, and online courses may not understand. Face-to-face courses allow teachers to impart knowledge to students as much as possible, and can also monitor students' learning status when they know it. Students can help solve problems immediately. Therefore, face-to-face training institutions are better, which requires you to personally go to the learning base of the training institutions for audition.
Whether the third training course integrates theory with actual combat. Compared with other industries, the IT industry values your hands-on ability more. If you only have rich theoretical knowledge without practice, it will be difficult to find a job, so a training institution with practical links is better.
To sum up, IT training institutions with good reputation, full face-to-face instruction, course content theory and actual combat are better training institutions.
