What do you know about real Mathforces? This is a world full of numbers, theorems and formulas. Are you ready for the adventure full of challenges and dangers in a new world?

Our friends from Harbour.Space University, the International Tournament of Young Mathematicians (ITYM) and St. Paul's International School Barcelona for the second time organize Tech Scouts — two week International summer camp for high school students. I really think it is a valuable and useful initiative.

For some participants the organizers cover participation fee, the decision is based on the results in special online math test and phone interview.

I invite you to take part in Mathforces: Tech Scouts Online Test 2018 (just fun and practice, unofficial, unrated). It was offered to candidates a year ago, in 2018. This year participants can use it as a practice. I think for many of you it will be interesting to compare your math skills. It starts on May/05/2019 11:05 (Moscow time).

The duration of the test will be 2 hours. You will be offered about 20 math questions. Each of them are expected to be solved using math skills. Please refrain from writing code and try to solve problems without any programming.

You can skip questions or re-submit answers during the test. All the answers will be judged after the test ends. Each question costs 1-3 points in case of the correct answer. Please, do not share your answers before the end of the test.

For sure, the test will be unrated.

Please refrain from participation if you have already participated in this test last year.

UPD 1: The problems will be in English.

UPD 2: The tutorials are published.
