There are plenty of websites available to prepare for this certification and become penetration tester but among all I found uCertify to be best among all.
The way the course is designed and presented very nicely: quizzes by chapters and knowledge area, readiness score, labs, chapters, and lessons, etc. The course will allow the learners to practice after going through each chapter and knowledge area in detail and test himself. The course will help you to prepare for your certification thoroughly. I encourage everyone who are preparing for Penetration Testing certification to go through uCertify courses and labs.
