As this course is for beginners and you explain most of the beginner's concepts but it could be even better if you also include things like: wifi,ethernet, fiber optics, network topology, etc.

The way of teaching is not so good you were just reading the content and delivering the easy explanation so its quite not good to understand for those who paid RS 499 for the page wise content else why don't they search on google instead of spending money here. I am not telling that you are not good but i don't like the way you teach ...need more explanation not the page wise reading. Thanks

- Please stop underlying the text and just use a pointer. - Please correct the spelling and grammar - Please use bullet points and then read the context/ content out. - Put cellphone or notifications on silent or Do Not Disturb.

Ich wusste, dass bereits alles und es war nur zu Wiederholungszwecken, dennoch bin ich nicht zufrieden, dass der Dozent auf Bereiche wie z.B PAN & GAN sowie verschiedene Bedrohungen z.B Viren nicht sehr gut eingegangen ist. Ebenso hat er in den PDFs (die er im Prinzip nur vorgelesen hat) immer alles unterstrichen, so dass ich wenn ich das nicht nur wiederholt hätte nicht mitgekommen wäre. Ebenso hat er wenig Bezug zur Praxis gehabt und das ist mMn sehr wichtig um die Thematik zu verstehen. Für Anfänger komplett ohne jegliches IT Wissen geeignet, für Leute die etwas Ahnung haben ist es leider etwas unterfordernd.

Worse course I have seen on Udemy. The guide/ instructor was reading some paragraph line by line, there is no interaction between us. And don't have depth of knowledge. Over all horrible experience. I was getting sleepy during this course, network security is a very intresting subject but the instructor was making so boaring

Please add some animation or examples so it can be easily translated to real-life experience. Great content so far.

Augustin-Ionut10 August 2020

Thanks for the quiz. I've discovered I have still much to learn about networks in general and firewalls in particular. Thank you also for the materials you have been presented.

Muy mala técnica de enseñanza, muy mal inglés, si no saben hablar inglés y pronunciar correctamente, no hagan cursos en inglés.

Karina30 July 2020

Poor content. It is very basic but maybe is because this course is not for professionals. Good teacher he does his best, good explainer but his english can be better. Anyway, he is making a good job!

Piyush30 July 2020
