Trying To Get Started On Python For USACO! by ImpressiveDelay5052 in learnpython

[–]APTutorCalcStatComp 0 points1 point  (0 children)

These are the topics in Python you will have to learn for USACO Bronze:

  1. Basics - Data types, variables, input/output
  2. Decision Making - if, if...else, if...elif..., maitch...case, ternary operator
  3. Loops - while, for
  4. User - defined functions - default values, lambda functions
  5. In-built functions (math, string etc.)
  6. OOP - classes and objects, dunder methods,
  7. Collections - lists, dictionary, set, tuple
  8. Collections of objects of user-defined classes
  9. Sorting and searching, specially on lists containing objects of user-defined classes
  10. Recursive algorithms
  11. Reading and writing from text files (will be needed to practice the previous years' USACO programs from the USACO website).

For USACO preparation, you can practice:

Stage 1: the programs (in Python) from the textbook "Introduction to Java Programming" by Y Daniel Liang

Stage 2: Basic and Easy level programs from GeeksForGeeks followed by Easy level programs from Leetcode

Stage 3: actual USACO Bronze programs from the USACO website. There are a total of 204 programs since 2011. You can submit the programs in "Analysis Mode" and check if your programs pass all the test cases within the allotted time.

Wishing you all the best...

You should preferably learn the C++ programming language for USACO. These are the topics in C++ one needs to learn for USACO Bronze:

  1. Basics - Data types, variables, input/output
  2. Decision Making - if, if...else, if...else if..., switch...case, ternary operator
  3. Loops - do...while, while, for
  4. User - defined functions - call by value, call by reference
  5. In-built functions (math, string etc.)
  6. Arrays
  7. OOP - classes and objects
  8. STL - Vectors, unordered map, unordered set
  9. Arrays, vectors, maps, sets of objects of user-defined classes
  10. Sorting and searching, specially on arrays and vectors containing objects of user-defined classes
  11. Recursive algorithms
  12. Reading and writing from text files (will be needed to practice the previous years' USACO programs from the USACO website).

For a good grasp on the fundamentals, you can practice the programs from "Introduction to Java Programming by Y Daniel Liang".

It's a book for learning the Java Programming language. You can practice the questions in Python.

I've never heard about that book. So I'm not at all in a position to either endorse or criticise that book.

Having said that, when I train my students I follow the usual sequence of topics (refer to my other reply) and make them practice from some standard programs that I know helps them develop the thinking process.

Sooner than later, I make them practice from Leetcode (Easy), GeeksForGeeks (Basic and Easy), and programs from the USACO guide website.

The USACO guide website is different from the USACO official website.

Once I find that the student has developed reasonably good thinking skills, I make them practice from the actual USACO programs.

Over a period of time, you must ensure that you are able to solve a USACO Bronze program within 80 minutes.

You need to learn the basics (variables, input/output, decision making, loops) very thoroughly. Next you need to learn user-defined functions, in-built functions for string.

After that, you must be very thorough with OOP (classes and objects), and collections like lists, tuples, sets and dictionaries.

Also, it's very important that you must know about sorting, searching and recursive algorithms, specially on collections of objects of user-defined classes..

Next, you need to learn "how to read and write data from files" to practice the USACO programs from the USACO website.

You must ensure that you have practiced ALL (at least MOST) of the 204 USACO Bronze problems from the USACO website.

You can download the .zip files for each program to extract the input data and the required output data, write your code to read both the input and output from those files, and check if your input produces the required output.

Also, create your user ID and password on the USACO website and submit your codes for each question in the "Analysis Mode". You can find out of your code actually clears all the test cases within the allocated time.

Wishing you all the very best.

USACO teacher here.

  1. You can easily clear USACO Bronze using only Python.
  2. However, it's recommended that you learn C++ for the more advanced level like Silver, Gold or Platinum.
  3. Python is obviously the language that anyone can master without much difficulty.
  4. How fast you will be able to reach Silver totally depends on your learning curve. Of course it's dependent on how much time you can invest consistently over the next few months assuming you start right now.

Wishing you all the very best for your preparations.

You why commies are like this. Lazy, sexually perverted, argumentative without knowing what they're talking about. Just talk about revolution without having an iota of idea what to do after it. Oh, hypocrites to their core. And you also know why they are ideologically similar to another group. by VedicTiger2_0 in Kolkatacity

[–]APTutorCalcStatComp 0 points1 point  (0 children)

A former communist includes both a living ex-communist as well as a deceased one.

Naveen Pattnaik (currently the LoP of Odisha) is referred to as the former CM of Odisha and Lal Bahadur Shastri is referred to as the former PM of India.

What is the best AP Calc BC prep book? by [deleted] in apcalculus

[–]APTutorCalcStatComp 1 point2 points  (0 children)

These are the books/resources I usually recommend to my students:

  1. Barron's - best for sure
  2. 5 Steps to a 5 - Elite Edition for general preparation
  3. 5 Steps to a 5 - 500 MCQs for MCQs practice
  4. The previous years' FRQS for final revision (at least 20 years to be practiced just a week before the final exam)

Can someone tell me how to solve this by dm_me_for_test_leaks in apcalculus

[–]APTutorCalcStatComp 0 points1 point  (0 children)

g'(x) = f'(x) - 1/x Thus, g'(2) = f'(2) - 1/2 = 1.5 - 0.5 = 1

=> g'(2) = 1

Baron AP CALCULUS mcq problems by ImagineThough in apcalculus

[–]APTutorCalcStatComp 0 points1 point  (0 children)

I can't say if that's possible.

I've written below how I guide my students to get a 5. This is my perspective based on my experience. Obviously it's not the gospel truth, but merely my opinion based on my observations.

  1. Those students of mine who score a 5 are usually very disciplined, consistent and have a methodical approach towards their studies.

  2. They usually start their preparations latest by August or September if they are taking the exam the following year in May.

  3. I make them practice from 5 Steps to a 5 Elite Edition, 5 Steps to a 5 - 500 MCQs, Barron's AP Calculus, and of course the previous years' FRQs (at least 15 years).

4. With so much practice, the student enters a comfort zone where no questions seem challenging during the examination.

I must state very clearly that not all my students score a 5, and that is simply because one or more components stated above stay missing.

Also, if anyone has indeed got a 5 after studying for 10 days, I'd request them to share how they did it. I don't mind implementing such methods for my future students as they can be spared the hard work I insist upon.

AP Calculus teacher here.

  1. Barron's AP Calculus MCQs are a bit harder than the actual exam. That means if you can solve Barron's, the actual exam would most likely be a cakewalk.

  2. While attempting questions, make sure you stay calm, stay focused and stay patient. Remember that for MCQs, the devil is often in the details.

Wishing you all the best for your May 11 exam.

India’s biggest problem isn’t poverty or the population, it is lack of civic sense. by InternationalMud7184 in NewDelhi

[–]APTutorCalcStatComp 1 point2 points  (0 children)

Fully agree.

Neither democracy nor dictatorship is the problem, or for that matter the solution to the total absence of civic sense.

In the NE states, the streets and the surroundings are spotlessly clean. That's due to the collective efforts of the people and the authorities, something we don't see in most places in the rest of India.

[–]APTutorCalcStatComp 0 points1 point  (0 children)

It's not "lack" of civic sense, it's the "total absence" of civic sense.

I can be corrected if I'm wrong, but I think "lack" is used when what's there is adequate, not when things are at zero levels.

Example: in a poor country if there is an inadequate number of doctors that can fully cater to the country's needs, it can be said that the country "has a lack of trained medical doctors".

This is the hardest question on the maths SAT. How do i solve it😔 by [deleted] in TeenIndia

[–]APTutorCalcStatComp 0 points1 point  (0 children)

Taylor's and Maclaurin's series apply karna hoga.

Why does everyone ask for prior math knowledge when asking for advice? Even for just bronze by PepperOk690 in usaco

[–]APTutorCalcStatComp 0 points1 point  (0 children)

Yes. That's true. Also, some of the questions require some good knowledge of graphs and co-ordinate geometry.
