Pinyin tests without tone numbers

Hi everyone
I am starting a mandarin course named HSK level 1,2…5
Everything is perfect. good translation and several native pronunciation for each character.
every 25 character in a level followed by another level just for learning pinyin.

every one can master the pronunciation by audio files and the pinyins are just a hint to remember how to read it ( and not how to exactly read it!). therefore strictly testing the tone numbers is a hurdle for pinyin levels.

I know that there are many characters with the same pinyin but different tone number. but I am learning pinyins just for typing and the pinyin-based keyboards do not need tone numbers.

In the pinyin levels all answers without tone number considered wrong.
If possible edit these courses that everyone can pass pinyin tests without knowing tone numbers.

I think many other learners have this problem.

Your future self will fondly recall the wisdom and foresight your current self was capable of the moment you decided to learn the tones. If you want to learn Chinese, learning the tones as well is an absolute must. If you rely on only Memrise to learn Chinese your pronunciation will be absolute shit, if you at any time in the future want to learn to speak Chinese correctly you will make it so much more difficult for yourself if you also don’t learn the tones correctly.
