    To Past Me,

    Linear algebra is not as scary as you think it is, despite what everyone has told you. Stay on top of your homework, even if that means finally getting medicated for your ADHD after months of doctor’s appointments.

    Focus on working in vector components; it will help a lot in your other classes. Also, get comfortable handling matrices, because you will panic and blank on many a test otherwise.

    Try to have fun! This class can be really enjoyable if you stay on top of everything.

    Love,

    End of Semester Liz

      Thank you for the tips! I will keep that in mind throughout this class

    • Iqra Khan

      Hey Liz! My name is Iqra and I am a current student in MAT 2580. Your letter has given me an idea of what I should look out for in the future of the class and I will make sure to focus on the vector components and get familiar with matrices.

    Linear algebra is very fun! It’s a super useful tool that will make a lot of the problems easier. It has tons of applications, like machine learning or computer graphics.

    Make sure to do your homework and practice the questions regularly. This will keep you on track and help you succeed!

    Enjoy the process and know that you’ll become more knowledgeable and confident by the end of the semester.

    Hey you! I’m you but from the future. I’m here to help you out. Linear Algebra is very scary but I need you to listen for I don’t have much time nor the words to help you out. Alright, so I got Exam 1 that you’re gonna get in the future, here are the answers and how to get them. You better master RREF and all these other concepts. This semester was rough for me so I’ll make sure it’s not as rough for you. Oh no, I’m running out of time. Just always do your homework before the next week. You have more time than you think, just dedicate a time slot to it each week, and you can definitely do that. The teacher will not extend the time for anything, not even Webwork! (Sometimes you gotta lie to yourself to apply more pressure so they can get things done). Ok, I gotta go, take care!

    • Angel

      Hello Joseph! My name is Angel, and I am a current student in MAT 2580. Your letter to yourself is helpful to me because it emphasizes the importance of staying on top of assignments and managing time effectively. I often struggle with procrastination, especially when it comes to challenging topics like Linear Algebra. Your advice to dedicate a specific time slot each week to homework is something I’ll definitely adopt this semester. By doing this, I can avoid the stress of last-minute work and ensure that I have a solid understanding of the material before exams. Thanks for the reminder about the importance of mastering concepts like RREF early on.

    • Titus Fan

      Hello Joseph, my name is Titus and I am a current student in MAT 2580. Your letter to yourself is helpful to me because I know for a fact that some of these concepts are complicated. I have taken this course before but I don’t remember much. There are many terms that I remember but don’t know the exact details of them like eigenvalue, eigenvectors, linear transformation, and as you mentioned, RREF. Also, thank you for the heads up on the stuff regarding WebWork (even though it seems it might not be true. Self-inflicted pressure works but shouldn’t be a constant).

    • Zu Kia

      Hello Lam! My name is Zu Jia, and I am a current student in MAT 2580. Your letter to yourself is helpful to me because I strongly believe that math is all about practice and time spent on it. Personally, for me, I’m a slower learner, so I always try to practice as much as possible. Also, thank you for the warnings, I will remember them as I take this course. It sounds like RREF is no joke… I shall go finish my Webwork now!

    hey me! Stay consistent by reviewing notes after each class and keeping up with assignments. Focus on understanding concepts instead of just memorizing them. Practice regularly by solving as many problems as you can, especially challenging ones. Don’t hesitate to ask questions in class or during office hours. Keep your notes and materials well-organized for easy review. Balance your studies with rest, nutrition, and exercise. Form a study group early, and remember it’s okay to make mistakes.

    • Alyssa

      Hello Gurpreet! My name is Alyssa and I am a current student in MAT 2580. Your letter to yourself is helpful to me because I struggle with not understanding some of my classwork and not staying behind to get clarification. Instead I would go home and stress about the work or the lack of understanding my work and try doing it on my own. I will really take your advice about joining a study group or even going to the tutoring center with the time I have between classes. How were you able to stay motivated in your classes??

    • STEMGIRLY

      Hello Gurpreet! My name is Kaylah and I am a current student in MAT 2580. Your letter to yourself is helpful to me because it emphasizes the importance of consistency and truly understanding concepts rather than just memorizing them. I’ve often focused on memorization, but I realize that understanding the material deeply will help me in the long run, especially with problem solving. I also like the idea of reviewing notes right after class, which i haven’t done but I will start this semester to reinforce my learning. The reminder to balance studies with rest and exercise is something I need to prioritize more. I’ll be incorporating these tips to stay on track and succeed this semester.

    • Ivan Rosas

      Hello Gurpreet! My name is Ivan and I am a current student in MAT 2580. Your letter to yourself is helpful to me because in my Differential Equations class I took last semester I applied most of the things you said in order to succeed. It’s good to know that I can continue to apply those techniques in order to pass this course. I’ll try attending office hours if I have any questions.

  5. Hussain

    Study for all the tests, and there will be material in the tests that will not be on the review questions/material learned in class. Always go to google for extra learning in this class.

    This class may seem easy at first, but moves to different materials very fast so do your best to keep up, you got this!!

    • DaneAR

      Hey Hussain. Thanks for the encouragement. I am honestly pretty scared of this course and am already on the edge of deciding whether or not I just want to give up and try again a different semester. I’ll try first though. All the best.

    • Jessica Gustave

      Hi Hussain! My name is Jess and I am a current student in MAT 2580. Your letter to yourself is helpful to me because I was definitely thinking that this course seems easy at the moment. Hearing that it moves to different materials very fast allows me to be prepared for when it does. I will definitely be using google for extra learning when it comes to this class. I’ll try my best to keep up by doing all the homework. The encouragement you gave your past self motives me to encourage my current myself.

  6. Roza Amanzhol

    Not just study the textbook as you do for your other math classes, but watch youtube demonstration videos as linear algebra requires imagination. Learn how to visualize given problems and see it in space. Before jumping to webwork before the deadline, try to deeply and completely understand the chapter. When it comes to study do not let things going on in your personal life get in the way because this class moves fast and it requires consistency. Eventually you will grow to love this class, because you love math and linear algebra is the basis of the field you are so interested in.

    • Alan Pacheco

      Hi Roza! My name is Alan and I am currently a student in MAT 2580. Your letter to yourself helped me because it gave me some really good advice on how to handle many of the problems I may encounter during this semester.

    • YihuaMei

      Hello, Roza Amanzhol! My name is Yihua Mei and I am a current student in MAT 2580. I agree with the way that you learning linear algebra. It is difficult to learn something only from the textbook. sometimes, we need to open our minds and use different ways and angles to learn more knowledge from other resources.
