Professor Serna was so amazing and when I mean amazing I truly mean it! He helped me for 4Weeks and he was super helpful as well as flexible with my schedule and he always accommodated meTo help me out. I passed my class with a B because the system of the online program was having issues but if the class would have been in person I’m sure I would have gotten an A. I am super happy to have found him through google and he is super friendly and very intellectual and knows so so much! If you ever need him to doubt in considering him because he will help you all the way to the end and willWork the problems out so that you can understand! Thank you professor you were amazing! I truly appreciate all you did and how you always encourage me of never giving up just like the stork you have on the wall! Thank you for truly being so inspirational to me blessing for you and the family it was a pleasure meeting you!

Amazing professor! Teaches the lesson very clearly so that you would be able to understand it easily. Would recommend to watch his videos. He also gives great examples that you would also encounter on your lessons. You will learn a lot from him.

I am currently taking online classes and Statistics is one of them. For those who are aware or online classes, its basically self-taught. I stumbled upon Professor Sernas video and I must say, his teaching was just so simple, concise, and easy to comprehend. I love that I didnt have to rewind anything at all. And also, his handwriting is so neat, a wonderful factor especially for anything Math related.

Thank you Professor for making truth tables understandable. Before your video I was questioning if I was in over my head in my logics class but now I understand and can help other students! You are wonderful.

Professor Serna is the best! He has tutored my daughter in Algebra 1, Geometry & Algebra 2. He is very soft & well spoken which made it easy for my daughter to understand. Perfect learning environment. Parents are allowed to sit in. My daughter left feeling confident, understanding the formulas and equations.

Professor Serna is an excellent math tutor. He explains every math problem thoroughly until you fully understand it. I would definitely recommend him!

Dear Professor,What happened to your website, also even the youtube channel doesnt show up.

Needed help on understand materials for an online Statistics 2 class. Professor Serna has a very flexible schedule and was more than helpful in making sure I was prepared for the final exam. Explains things really well, and would recommend if you need help understanding math!!

What I like about Professor Sernas lectures on youtube is that his lectures explain the underlying or sometimes hidden concepts also, and that makes it very interesting.He made me think about something, so I asked him a question, and he was very gracious and replied back very clearly in the comments section.He is also generous in his answers and the way he explains different topics.I feel he is the best, he is God gifted in his ability to make other people understand clearly.

Amazing Professor! He really works with you teaching easier methods to answer problems! He is very patient and knows what he is doing. I would totally recommend him to anyone that has a hard time with math and needs a little extra time to learn !

An excellent teaching style.Very nice videos on YouTube.If you want to get help on any topic, and you find his video on YouTube for that subject, watch it, believe me it will help you.

The best math tutor I have ever had. Goes through everything step by step. Very professional and flexible with his schedule. If you need help in any type of math go to him!!!

Such an excellent tutor! I would seriously consider visiting him as soon as you know you need help. He knows math like the back of his hand and explains everything very well! A+!

This work is of high quality. It is the best of works. The explanation are very clear to comprehend and it makes one to love the subjects at hand. Thank you professor Serna.

There are no words to express my gratitude really. I was literally failing my stats class until I found Professor Serna. I passed the class with a 100%!!! And now that I am in more advanced classes stats is what comes the easiest to me. He is AMAZING! Teaches with patience and passion, knows the material better than college lecturers. A big big big thank you to Professor Serna!

Great instructions! I spent a couple hrs trying to understand my book. Recommend anybody that needs Discrete Math help

I watched professor Sernas video on Welchs 2-sample t-test. As somebody just getting into statistics I found the explanation to be very clear and detailed. What was particularly useful for me was that he included explanation of how to interpret the results once all test values were calculated. This was missing from a lot of other videos and articles I found on the topic.

I recently watched his youtube video about probabilities and Mr Serna helped me so much. He has a very clear speech, he is understandable in his way of teaching, and explains efficiently the theory.Someone like me, who wants to remember the basics, and English is not my native language, i believe that this is one of the best videos demonstrating a nice, well put-together and connective content.

I spent a week reviewing and glazing over an introduction to logic course I was taking online. In an attempt to get a different explanation I searched for Propositional Logic videos, using YouTube, and found Prof. Serna. After watching one video, it was as if someone turned the light on in a dark room.

Professor Serna is the best math teacher there is, especially if you are dealing with statistics problems that are out of this world. When you are having issues grasping the math concepts he will help you in a manner that is down to earth and he will walk you through the whole process until you feel at ease and all the anxiety is gone. There is just no substitute, Prof Serna is the best!!

He explains the material in such a way thats its easy to understand. Its not going too fast or too slow, and the notes he takes are helpful!

I have watched a couple of his videos on youtube and they are all brilliant. He is a very knowledgeable person and a fantastic teacher!

Excellent teacher, I watch his videos on YouTube and he breaks things down in a way that is easy to comprehend and useful at the same time. I highly recommend Prof. Serna.

This professor is fenomenal. Im 48 years old back home n school and God only knows that with out professor Serna I would not have been able to stay in school. His statistical methods and experience is above all I have even seen on YouTube. You will not go wrong here. The ease of learning is exemplary and so is his professionalism. Thank you professor Serna.

I was having a hard time in discrete math and Professor Serna helped out a lot with his video: The introduction to logic. He explained it so well.

Was going through his logical reasoning videos on Youtube, I found his teaching style is normal paced, clean and easy to understand!

Very few people can explain complex concepts in a very constructive and detailed manner . A great teacher indeed

Helped me learn logic very easily. Very calm experience yet still detailed.
