Here FE 2024. I just passed the FE Exam on my first attempt. I can be more proud.
Thanks so much MARK for all the Free useful videos that you have put on this channel. These resources were instrumental in my preparation journey.
I would like to give a few tips to future people planning to take the FE.
Initially, I started my preparation on Mark's channel, but I found some of the problems to be quite challenging. Seeking additional guidance, I explored various channels until I stumbled upon @Genie Prep. Her channel features a comprehensive playlist covering all the subjects outlined in the FE specifications, except for the construction part. Working through problems alongside her, I found clarity and deeper understanding.
Returning to Mark's channel after engaging with Genie Prep's content, everything made so much sense. Both channels emphasize effective utilization of the handbook, which proved to be immensely beneficial in grasping key concepts.
In my opinion, the combination of Mark's and Genie Prep's channels is sufficient for passing the FE exam. However, for those seeking further familiarity with the exam format, I recommend practicing with NCEES practice exams, as I did.
For Problem 18: Shortcut using TI-36x Pro.

thank you
thank you so much
I just wanted to tell you thank you. I took the test the past Nov 14th and I just got the result today and I successfully passed it. It was hard for me studying for this test. I’m from Colombia and no just the language but the content of the test kinda worried me a little bit but your videos were EXTREMELY helpful. I cannot say thank you enough, thank you for helping everyone that cannot afford an expensive FE course. Loved your videos and your explanation I wish all my professors back home were like you, school would’ve been way easier and way more enjoyable. Thank you again 🎉🎉🎉
Thanks for the kind words! Congrats!!! Dios le bendiga!
did you only study this course? or did you use other stuff to study?
did you find the level of actual test's difficulty similar to the examples provided here?
Good luck
For Question #8 you can go to page 39 where area of parabola is listed. With this you can split the shape into the 8x6 = 48 m^2 rectangle and create a parabolic shape where the [ A = (2*b*h)/3 ] and b = 8 and h = 6 where A = 32 m^2. Using these two areas you also get 80m^2 which was much faster and easier.
For question 8, you could "complete/close" the rectangle and get an area of 12m*8m=96m^2
Then find the area of the bottom right parabola you get when "completing/enclosing" the shape into a rectangle by using the formula A=b*h/3 on page 39 of the most recent FE Reference book.
This results in an area of 8m*6m/3=16m^2.
After doing so you take 96m^2 - 16m^2 = 80m^2
Nice catch :)
Could have also taken the Parabola equation and added it to the area of the square.
2*8*6/3 = 32
6*8 = 48
32+48 = 80
Both are good!
Thank you mark. My FE result came today and I passed. Just letting you know that your videos have been great help for me in this journey. I'm entirely grateful to you for being such a fun teacher.
I'm happy to share this news with you. I've been notified by NCEES this morning that I PASSED my FE exam!!! This is a milestone for me and the past week is definitely been one of the most torture weeks of my entire college career just waiting on the result back. Thankfully, it turns out great after all the preparation during the whole winter break. Thank you for your contents they are REALLY helpful. I didn’t study anything else but this and the FE official practice problem.
Do you think following this course will be enough to pass the exam?
ive been crawling around your first 2 videos and website for 5 minutes. I'm impressed and grateful. Thank you.
Thank you very much for all your effort in making these videos, it really helps for lot of people. Really appreciate you doing this!
Thanks Mark, I came across your videos while looking for resources and they've been super helpful. Even though I don't have your calculator, it's helped recognize which functions the HP 35s may be capable of too!
Amazing works! Thank you Mark for your help and tutorial in FE Exam Review Sessions. Keep it up!!
Solivng question #20 using the TI-36X Pro calculator:
Press 2nd stat-reg/distr.
Go-to DISTR tab.
Select #5 for Binomialcdf.
Input: x = Single | Trials = 5 | P(Success) = 60% or 0.6 | x = 3
Select Calc.
You'll get 0.66304 (the same value as from the table shown in the video.
Take 1-0.66304 = 0.33696 or ~34%.
From Colorado Greatly appreciate these videos and enjoy your teaching methods.
Hi Mark, I just recently passed the FE exam and wanted to express my gratitude for sharing your videos. It's really super helpful and took big part for me passing the exam. Thank you so much.
Thank you mark !
It was very very very helpful.
Thank you so much and YESSSS!! this review is a big help !
Glad it was helpful!
This helped me so much! thank you!!!!!!!!!!!!!!
Thank you! Luis from Venezuela taking FE pretty soon
Great video, thank you so much for all your help.
I just wanted to say for problem 8, I started off the problem by getting 10 as well using similar triangles but the next step I did was use law of cosines to get my angle from the triangle formed in the circular segment(11,11,10). That's how I was then able to get my circular segment area and combined that with the area of the square and triangle. I hoped that helps
Hello Mark, thanks for these videos which were extremely helpful. I passed the FE today after 10 years out of BS degree.
Thank you so much Mark. I passed the FE exam today on my first attempt. Your videos help a lot. I watched all your review session and bought an exam sample on NCEES site.
My biggest struggle with this test is time management so seeing the calculator tricks is amazing. Thank you
Hi Mike, thanks for those useful videos! I wonder whether you have any recommendations for books which can have more problems to practice?
Hi Mark. I love the content of your channel . I am wondering if the computer based exam would allow one to use paper and pencil to do math or draw.
Thank you!
great content and lesson. Just remember to remove the calculator after you finish a problem.
Thank you. Ruth From Ethiopia in U.S
Thank you so much
Appreciate it! Mattson 🇳🇵🙏🏻🇺🇸
for Q (8) FERH page 113 look for half parabola under area and centroid formula is 2(ab)/3
Thank you 🙂
As per fe reference manual, the equation for linear regression is y=A+Bx , as opposed to y = AX+B
Thanks for this , I noticed that as well
Addition is commutative, and it is arbitrary what we call the constants.
He was using what’s In the calculator which is y=ax+b, check out 1:30:16
@17:03
Just calculate L.H.S of equation 1 with the answers and check if it matches R.H.S.
Right answer should five you L.H.S = R.H.S
Thank you very much for this effort , i was wondering if i can find theory explanation before addressing examples , i've been working as design engineer for 14 years and i'm bit away from books for a certin period of time , what's your recmmendation to reveiw the theory ?
Thank you
Hello, for question 20, explain again how or why you chose 0.6630 from the Cumulative Binomial Probabilities table?
You can solve question 8 by adding the rectangle to the curve equation 2/3 bh
I tried on my Android device and it works. Thanks buddy.
Hi Mark, In question 11, you equalized f1 and f2 because the 2 functions are intersecting and to find the intersected points?
I was wondering for the marble problem why I can't do 1-(2/5)(2/5)(2/5). Total probability minus the probability of getting 3 reds?
What page are the indefinite integrals and derivates on? I think they might have taken them out of the handbook for the recent exams.
Maybe I'm not cut out for engineering lol. I tried to work out these problems ahead of you by pausing the video and using the handbook and idk if I got a single problem right.. I graduated 3 years ago so jumping back into this is very difficult
Hi Mark thank you for your CZcams. I am watching your Mathematics . But FYI please , can you do minor correction for #13 and 14 question. Just add k after 4
for problem 10, is there a way to solve that using ti 36 pro??
Are the questions you are solving in your videos similar to the ones on the Civil FE Exam?
I use the same calculator and find it helpful watching which buttons you use. Maybe more light on the calculator and go slower so we can know which buttons to press. Thank you!
Thanks for the tip! I will try to do that for future sessions.
This is a good work
Thank you, please always explain concepts not just solve.
Hi Mark, Thank you so much for this video. In question number 18, how do you know a sample size is 1? Thank you.
hello Mark, for #17 , are we supposed to calculate sample standard deviation or Standard deviation ?
Unless you know every single number in a given population, you typically use sample standard deviation. Concrete break strengths are typically a small sample from a larger population or set.
For Area A2, how can get 8.07 m^2 since Phi=.94 to calculate the area=R^2X[Phi-sin(phi)]/2= (.92X11^2)/2=55.87 m^2
Please clarify.
On #18 for the Zvar equation, why did the μ and X̄ switch places? Is it only so that the Zvar remains positive? Because I don't see a negative Unit Normal Distribution table in the FE handbook.
Essentially, yes. You'll also notice the diagrams for the z-var tables are opposite as well.
At 42:50 Question 8, you used area of trapezoid formula. Is this formula, along with other area formulas found in the reference manual? If so, where?
See page 111 in the Reference Handbook v10.1 for general shape formulas.
If I were to use the TI-36Pro to solve would I use BinomialPDF or BinomialCDF?
BinomialCDF
On Question 19, the formula on the handbook says y=a+bx and on the video the problem is done y=ax+b and we get 2 different answers. Is the formula on the handbook wrong?
From what I understand it's because Mark uses a TI-36X Pro and that calculator uses Ax+B. I use the casio and it's the same as the book, however I'm also still stuck on what to do if the equation is different. Have you found out what to do?
For #19 my A value is -2.84 and my B value is 2.44. Not sure what I did wrong. Using the casio fx-115es plus
Good question. This is the value of practicing with your own calculator as the two are different!
The Casio uses A+Bx format for linear regression.
See support.casio.com/pdf/004/fx-115ES_991ES_Eng.pdf
The TI-36X Pro uses Ax+B.

@@MarkMattsonPE Thank you! I found out that the variables are switched on the casio
Don't questions 13 and 14 need to have a k in the formula for vector B in order for the math to work out to the chosen solutions? Otherwise the matrix for vector B should look like [2 , -3, 0], no?
ahh he mentions the k is missing a little later in the video
I just don't get problem #7. I understand similar triangles, but this one is complicated for me. Anyone have an additional resource I can watch?
i dont get that one too, did you find anything on it?
@@sheed2819 I just saw this. I did figure it out.
#1) Take triangle ABC. The only side missing is BC. Use pythagoreas theorem to find BC = 13.
#2) Using similarity between the triangles, you can prove that ABM ~ CBA (They're similar triangles).
#3) Because they're similar, you can set-up ratios between the relationship of their sides to solve for the missing lengths. The first length, for example, would be solved with the following ratio: BM/BA = AB/CB => Solve for missing side, BM = 25/13.
#4) At this point, you could use two more sets of ratios to solve for AM and CM. For the sake of time, you might have realized that the only answer that contains 25 is B.
#5) If you found all similar sides, the denominator for all three is 13 so you can just multiply it out of the ratio to get the answer is B, 60:25:144.
If you want additional help, this video from Khan Academy contains a similar problem: czcams.com/video/LrS5_l-gk94/video.html
The first time I took the FE, I was told that the TI-36X pro calculator was not allowed due to being able to type letters. I emailed a complaint to NCEES and about two weeks later I got a refund. One of the sections where I didn't meet the average was mathematics which was frustrating.
That's ridiculous because it states on their website and in the FE Exam Info by NCEES that the TI-36X Pro IS allowed, so you should've just been able to show them that, and they should've let you in. Anyway, glad to hear you at least got a refund for your unfortunate situation
Mark you should do use the calculator step by step because there are many who don't use this calculator and need more details please. Thank you.
Thanks for the suggestion. I'll try to illustrate its use better for future videos.
Hello everyone, I am preparing for FE Mechanical. CBT exam specifications for beginning from July 2020 examinations doesn't mention Trigonometry under mathematics topics so during exam does they ask questions on Trigonometry?
As I can see a lot of materials online solving Trigonometric questions.
Thank you!
Could you include an answer key to the last page of pdf. That way we can quickly check our answers to determine which problems we need to review.
i'm failes FE 2 time since not study let see for this time will back to comment that i'm pass FE
Q14: the correct answer should be option B?!!! can someone confirm please.
no its option C
wow
it will be better if you take the calculator off please
