INSPIRATION

GUIDELINE

In university, we learned C and C++, so I thought learning C# would be easy with just online tutorials. That’s why I wasn’t interested in joining a paid C# course. But at Devskill, the ASP.NET course requires a 4-month C# course first. At first, I felt it would be a waste of time—until I actually started it. Jalal Sir’s teaching is on a different level. He explains everything clearly, step by step, using real-life examples. He makes hard topics easy to understand. Honestly, no one has ever taught me this well before. He also shares knowledge about the software industry and keeps us motivated throughout the course. Now I understand how important C# is for ASP.NET. My OOP concepts are clear now, and I’ve also become more active on Codeforces. Thank you, Jalal Sir, for your great teaching. If you’re thinking about skipping the C# course—don’t. It will help you more than you expect.

I recently completed the DevSkill C# Batch 20 course under the guidance of Jalal Uddin sir, and it has been one of the most rewarding learning experiences I've had. The course covered very advanced topics that are rarely discussed in other platforms. Jalal Uddin sir is not only highly experienced but also extremely friendly and supportive. Unlike many online platforms that feel like business centers, DevSkill truly focuses on student learning. The environment is interactive—students are encouraged to ask questions multiple times without hesitation. I’ve done many courses elsewhere, but DevSkill stands out for its depth, sincerity, and quality of teaching. I’m genuinely thankful to DevSkill for offering such a professional and enriching learning journey.

Alhamdulillah, I have successfully completed the course "Professional Programming with C#". I have completed my diploma in Electronics Engineering, so I was a non-CSE background student, but currently I am doing BSc in CSE. I am a C# .NET developer, being a non-CES background student, I was very weak in the basics of C#. After completing this course I can say that now I know all the basics about C# very well, which will help me further in my journey in this field. Finally I can say that all these good aspects have come in my life by getting a best trainer like Md. Jalal Uddin Sir. His dedication, teaching style, syllabus and his motivational speeches are all like antibiotics. Thank you Sir.
