I think Devskill is totally different from others training institute of Bangladesh. Their syllabus and and training mechanism are top class. Our trainer Mahedi vai, explained every tiny topics briefly and he never shown anger when someone asked simple things he already explained. That's how we got proper and deep level knowledge. Linux System Administration course is highly recommended for beginnerd.

To my personal acknowledgement, this course itself has been tailored and delivered into the most positive of user friendly manner, as humanely and professionally possible. The modules are easily convenient to learn and further meditate upon, even for someone with little to no prior knowledge about system administration. My experience and correspondence with Mahedi Sir during the entirety of the course has been most pleasant and productive by all means. Truly, it is a very difficult undertaking for any seasoned industry veteran to put themselves into the position of a entry level learner/practitioner and hold patiently, a steadfast resolve to build upon the foundations of knowledge and expertise from scratch. But to my surprise, our course instructor has been very successfully able to break down every learning components into much more meticulous details and explaining/demonstrating them down to the last syllable. This eventually broadened the learning curves greatly and left little to negligible gaps between the ongoing lessons. Mahedi Sir was also patient enough to tolerate and cope with our unacceptably slow progress and even went out of his way to withhold some classes for additional time period, and even considered to host an extra class !

Alhamdulillah, I am very much satisfied with this course. The way this course has been designed and topics covered, that helped me to learn Linux very deeply. The instructor of this course Mehedi Hasan vai is obviously an expert in this field and very knowledgeable, the way he tried to teach us is appreciable. He always tried to give us a clear idea, and responded politely to every question, it was great to be able to learn from him. Thanks Dev Skill to offer this kind of course with very good instructor.

বড় বড় টপিক গুলো ধৈর্য্য ধরে বুঝানো এবং আমাদের বিভিন্ন ধরণের প্রশ্নগুলোর উত্তর দেয়াড় জন্যে অবশ্যই আমাদের মেহেদি স্যারকে ধন্যবাদ। (যদিও অনেক সময় আমরা অনেকটা মাথা গরম করে দেয়ার মত বোকা বোকা প্রশ্ন করতাম) আর আমি মনে করি সিস্টেম কিংবা নেটওয়ার্কিং নিয়ে যারা স্টাডি করতে চান তারা ছাড়াও প্রোগ্রামারদের জন্যে এই কোর্সটি বেশ প্রয়োজনীয় বলে আমি মনে করি।
