Thank you Sam and CertFirst for delivering a great 1 on 1class on a short notice. I was going to loose my job if I did not pass my exam before the deadline given to me. All the support I received from the CertFirst team and excellent Virtual live instruction from Sam during these COVID crisis, I was able to pass the exam at my first attempt. Thank you so much CertFirst as I cant be more satisfied and will recommend you guys to all my friends.
