Today I have exam on cyber security and I really regret the fact that you haven't made any lecture vedios on the paper cyber security and unix. I passed my previous sem papers by only going through your videos and scored handsome result. Today I again visited your page to clear firewall which is on cyber security. Again I want to thank you for your efforts and making things so clear. ❤
