Studying English for a test on Holy Shabbat

My Telita family wants to learn English on Holy Shabbat.
She has no pleasure or joy in this, but only a desire to get a good grade on her exams.
Of course, not for the entire Shabbat, and there is a decent amount of time dedicated to prayers in the minyan, Shabbat hymns, Torah readings, Torah study, etc.
But in my free time
Maybe it can be allowed?

After all, if she knows English properly and correctly, she will be able to enlist in a unit with more important tasks for the defense of the people.
And later, you will be accepted at the university for more beneficial majors for the protection of the people, their development, their success, and their prosperity.
In other words, talent that will ultimately lead to more protection and settlement of the Land of Israel
There will come a rabbi (rabbinic?) of the settlement of the Land of Israel who will weigh against all the 313 commandments (see the books of P.) and reject the rabbi’s rabbinic practice of preparing from Shabbat to the day of rest.
(The question is for all the inhabitants of the land, although my family may be a little less so, because we fear that the corruption, corruption, and Messianic ignorance of the Bibbites and their consequences will bring destruction and annihilation to the inhabitants of the land in the medium term, and we at home are waiting for European passports, and if God sees that the situation is getting worse, we will flee in time, so that for us it is doubtful whether there will really be any practical benefit to the settlement of the Land of Israel or if God will force us to flee, and if the situation will improve, and the question is about those who do not think of fleeing, whatever it may be)

Another reason to allow studying on Sunday for the purpose of a test
After all, studying for a test is permitted because it is a mitzvah.
And behold, when you gather your grain and your wine and purify yourself in the Land of Israel, it is a mitzvah like putting on tefillin, at least according to the Hatzas, in the Sukkah.
Therefore, secular studies are a mitzvah in the Land of Israel and should therefore be permitted.
 
It seems to me that studying math and English these days is an occupation no less important than picking grain or apricots.
 
Am I right?
