Just a couple of days away from taking my the first essentials exam, have to say keep up the good work, found your videos really helpful and have refreshed and picked up on a lot of new stuff as well.
Good Luck on your exam. Make sure you get a good night's sleep the night before and a good breakfast the day of the exam so you're not distracted by hunger pangs. You'll have to post back and let us know how you do. Maybe you can add to the Professor's thread on exam tips.
Congratulations on your pass. And a very good score as well. Most of what I've heard is that the 220-602 IT Technician exam is very similar in nature as the Essentials. Maybe a little more directed toward the soft skills. Scoring as you are, you should have no problems.
Congrats on the Pass!!!! IT Technician exam is more in depth of trouble shooting. Follow the exam objectives for 602 you will be right. Also it's good to do practise exams to see where you need improvement but don't just memorise the questions but actually learn them, hope this helps good luck.
