I skipped my class of 1h45min to watch a video of 5min that made me understand my whole course
Thank you so much

[omarazab]

My instructor taught that lesson in a one and a half hour class and I just understood it in a 5 min. video !
You are amazing thank you !

[Daniel_Montenegro]

You explained me in minutes what the course I enrolled in couldn't using: 30 pages, 2 Video Lessons and 1 Live Class.
Thank you!

I spent all day reading PMBOK and another PMP text book until my head was spinning & then I found this. Thank you, thank you, thank you!!

I'm an engineer, and I used to think that I can explain ideas clearly. But after watching your videos, I've learned a lot from your gradual, cumulative and clear approach. Thanks a million!

[elizabethogle]

You explain this way better and more clear than my textbook for the class. THANK YOU!!!!

I pay F 6000$ per semester. And you made my life so easy without losing a penny. Your a legend!!

[sarahlui]

This was a great explanation! How early start and early finish is calculated is so clear to me now and now I understand this is what the forward pass means. In so many teachings they always make it sound like something completely different. Thank you for making this video possible! Now to watch how Ls and Lf is done.

[cristinacarreiro]

God this was explained so much better than what I learned in class! The book doesn't help either just gives a bunch of confusing equations lol thank you! You're a life saver! Thought I'd be on this assignment all day!

[jessicaperezvelazquez]

Lifesaver! I didn't understand this concept in class the other day but this helped me so much, I understand it clearly now.

[tannupriya-jhkf]

you are a saviour. i have my exam coming and your videos helped me alot.

[jamescavalari]

If activity A starts at the beginning of day 1, which is called "0", and it ends at the end of day 5, then activity B would start at the beginning of day 6. So when you write "5", it represents the END of day 5, which is the same as the BEGINNING of day 6? So the numbers in all of the boxes in the top left and top right corners represent the END of the day of the number. (I don't know if this is a question, or if I'm just typing this just to type it.)

9 years and still better than my long complicated lecturer explanation, thanks bro

[creeksideapartments]

My professor spent 90 minutes and I learned only 20% of what he said, here we go with this video, I learned 100%!

[soyusmaximus]

Thanks for this. I'm taking an online class, and of course the Professor just gives us some vague Powerpoint presentation to base our homework assignment off of, no lecture or reading.

[mahbubhassan]

My Teacher Taught me the same things in 2 hours class. How easily you teach us..thanks

[kelvintoroitich]

you are my Lifesaver with my exams in a week time I'll be more than ready to tackle it

[shufengyu]

Question, does activity B start on day 6 or 5? Because it takes 5 days to finish activity A, then the following NEXT day to start activity B? So is Early start for B, 5 days or 6 days?

[anox]

Great videos, working on my CAPM now and this is a great resource! So thank you. Question, where are your durations coming from? Those are the PERT formula outputs?

[sebastian.herrera]

THANK YOU SO MUCH! BETTER THAN MY PROFESSOR!
