Yeah, the advice get insulted
Farrukh Nizami is piece of crap, no good. I took his course because my brother asked me to and I was ahead of him so I could compare his teachins and he was just passing time, good for nothing. Want to waste your time and money? go for any institute whether cttc or ssuet.
My advice just concentrate on BSc first, then when you have plenty of time and interest, dedicate yourself to CCNA studies. You can do it, its not rocket science.
BTW I will be giving my last exam for CCNP inshAllah on 8th Oct hopefully. For that I have planned to cut myself from everything until I nail it down and for that my page on facebook wont be able to see the dawn of 1st October 2,448 people will have no clue where the page has gone
And yes to be focused on something, just get insulted
