When I was at school if you wrote all the correct answers in a maths paper without any workings you wouldn't get more than maybe 60%.

VC(t) = ϵ(1−e−t/τ)

There may be a kind of analogy here with natural language. When I read and write, I don't see words as a group of letters, I seem them as pictures. Hence I quickly sense if a word is spelled incorrectly because when I see it the picture looks wrong.

When I look at the equation above, I also don't see a formula, I see pictures. I see voltage as a function of time, and I see that being a small number scaling a first order rise with a given time constant.

(If ϵ does not actually represent a small number, then that would be a poor choice of symbol in the equation.)

I just see letter and numbers. I read ϵ and e and t and τ the same. Then there's the nonsense of having lower and upper case in the same formula. It's even worse when I write it down because my handwriting is very slow and scruffy. My hand doesn't do as it's told and sometimes I just randomly write the wrong letter for no reason. I was diagnosed with dyslexia, but probably have dyspraxia, as my reading is fine.

Mathematics is great in that it's either right or wrong, which isn't the case with other softer subjects, but that means there's less room for error. I can misspell words and the sentence still makes sense, but miswriting a symbol or number would lose me more marks.

If you get all answers correct, you would get 100%. There is a marking scheme with marks allocated to each question according to each part of the answer that needs to be provided to obtain the marks. For someone to get 93% that means that marks were dropped somewhere, probably due to not providing some expected element of some answers, or maybe by being incorrect in some answers that were given.

Unfortunately, mathematics is not what is used to be in the minds of some people. Get a load of this nonsense.

OK, so you literally can't comprehend the formula. Shame, but that the "fault" lies with you, not with maths or the notation.

Frequently lower/upper case is used to convey information, by conventions. For example, in my first week at university my "Senturia and Wedlock" textbook section 2.3.4 is "Notation Conventions" indicates these conventions are in widespread use...
General network variable: vA, iC
DC component of a waveform: VCC, IB
Peak amplitude of a sinusoid: Va, Ic
Incremental component of a waveform: va, ic

My handwriting is becoming appalling :( Age and keyboard use are the main points, but a traumatic biceps injury didn't help.

WOW.  In these four pages there is a small amount of truth and potential added value.  Buried among a lot of trash, and wit much opportunity to misunderstand the little that is useful.
