Even needs to be moved in front of be.
With my limited knowledge of English, it doesn´t sound natural for me to have "even" in front of "be", therefore, I have put it after it. I´m not saying, of course, that your suggestion is wrong, don´t get me wrong. I´m just saying I personally find my current location of "even" fine. Anyway, thank you for pointing it out.
After elsewhere your grammar is pretty bad.
A sentence structure has been changed - a hyphen has been added. I hope it is better now.
Instead of saying 3x3 stickers you should use nine stickers.
Is saying both also OK for you?
I would capitalize everything on this list. You should also capitalize each word in the titles of your sections.
Although I am aware of this capitalization phenomenon (let this forum be an example) even in some English-written newspapers, other English-written newspapers don´t use this phenomenon and so is not a wikipedia. What´s more, as far as I remember, I think I never saw this phenomenon in case of scientific (physics, to be more specific) English-written papers. Therefore, I reached a conclusion the capitalization is not a strict rule. Unless strong arguments for a capitalization are given (preferably with an explanation why it is not used in scientific papers), I am going to leave it as it is now.
Even though technically you should use may over can here, using may makes this sentence sound really formal.
As long as it is not a really serious grammar error, I am fine with it o_O.
Using an adverb on skip is kind of weird. Usually people just say that you can skip something.
Maybe I am misunderstanding you on this one, but "this part" may be skipped in "you may calmly skip this part up to the pair of cube images with letters". That being said, I believe I use "skip something" in accordance with your suggestion.
I assume you are using quotes around skilfully to convey it's not actually that skillful.
Well, for beginners it is not a piece of cake at all, I would say. After all, some skills are required, since you must be thinking/planning in order to achieve your goal.
Final consequence doesn't realleiy fit there. Consequence has a negative connotation. A consequence is something bad that happens as a punishment for doing something bad. Using the word final make it really dramatic.
A "consequence" replaced by an "effect".
For me, it is hard to believe a consequence has a negative connotation. Consider this sentence: The Sun is shining. As a consequence, there is more light in comparison with night. More light certainly is not a punishment and a shining Sun is certainly not a bad thing, I would say.
Thank you for pointing it all out. Since I am not capable to see these errors, I would be grateful for telling me more of them.
And as a bonus, the
corners-first method has been translated into English.
