Subject genders + Pflichtfach/Wahlfach
Subject names do not share one gender — each is a normal noun with its own article. -ik names are usually feminine: die Mathematik, die Physik, die Informatik, die Musik (also die Chemie, die Biologie). -isch names are neuter: das Englisch, das Deutsch, das Französisch. Others are lexical: die Geschichte, die Erdkunde, der Sport, die Kunst. Compounds on -fach: das Fach (subject), das Pflichtfach (compulsory), das Wahlfach (optional).
School-day nouns; "Hausaufgaben" is plural
Core school-day nouns with article and plural: der Stundenplan, ¨-e (timetable), die Stunde, -n (lesson), die Pause, -n (break), die Klassenarbeit, -en / die Prüfung, -en (test/exam), das Zeugnis, -se (report), der Lehrer, - / die Lehrerin, -nen (teacher). die Hausaufgaben (homework) is normally plural: Ich mache meine Hausaufgaben — never "eine Hausaufgabe" for homework in general.
Classroom items + modal rules + opinion frame
Classroom items (article + plural): der Kugelschreiber, - (pen), der Bleistift, -e (pencil), das Heft, -e (exercise book), der Rucksack, ¨-e (school bag), die Tafel, -n (board). Rules use modal verbs with the infinitive at the end: man muss die Schuluniform tragen; man darf das Handy nicht benutzen (the Handyverbot). Opinions follow a frame: Ich finde [Fach] + adjective, weil... — adjectives: interessant, langweilig, anstrengend, streng.

Pflichtfach is not Lieblingsfach
Both end in -fach but answer different questions. das Pflichtfach (from Pflicht, duty) is a subject you are required to take: Mathematik ist ein Pflichtfach. das Lieblingsfach (favourite) is the subject you like best: Mein Lieblingsfach ist Kunst. A subject can be both, so don't treat them as opposites — "must you take it?" vs "do you like it best?".
Speaking (Paper 3): Pflichtfächer named as a recognition gap (s22 Topic 6).
After "ein" the adjective carries the ending
ein (and kein/mein) shows no ending in the nominative masculine singular, so the ADJECTIVE must carry the case/gender marker: ✗ ein streng Lehrer → ein strenger Lehrer. With the definite article, which already shows gender, the adjective takes the lighter weak ending: der strenge Lehrer. Dropping the ending altogether is the most basic adjective-ending fault.
Grammar/Accuracy: adjective endings named every sitting (s22 42/43; w22 42; s23 42/43; w23 42).
Movement verbs take "sein" in the Perfekt
gehen, fahren, kommen describe a change of location, so their Perfekt uses sein, not haben: ✗ Ich habe zur Schule gegangen → Ich bin zur Schule gegangen. The participle gegangen is not the problem — the auxiliary is. Examiners flag this for fahren (ich habe ... gefahren for bin gefahren); the same rule covers the school commute.
Grammar/Accuracy: wrong auxiliary, ich habe ... gefahren for bin gefahren (w22 Speaking; s23 42 Accuracy).
"Hausaufgaben" is normally plural
German treats homework as a plural set of tasks: die Hausaufgaben. Say Ich mache meine Hausaufgaben, not a singular "eine Hausaufgabe" for homework in general, and match a plural verb/article to it. An invented singular for the everyday concept flags a candidate has not learnt the word as it is actually used.
(general FL trap)
Modal rule: infinitive goes to the end
A modal verb sends its infinitive to the very end of the clause: ✗ Man muss tragen die Schuluniform → Man muss die Schuluniform tragen. The modal (muss/darf/kann) sits in second position and the infinitive (tragen) closes the clause. This bracket is essential for stating school rules and is a common slip when translating directly from English order.
(general FL trap)
"weil" sends the finite verb to the end
Subordinating conjunctions like weil (because), dass, wenn and obwohl send the finite verb to the very end of their clause: ..., weil wir jeden Tag Hausaufgaben bekommen. ✗ ...weil wir bekommen jeden Tag Hausaufgaben. Keeping verb-second order after weil is a frequent word-order error in opinion sentences.
(general FL trap)
Not every subject is neuter like "das Fach"
Because the umbrella word das Fach is neuter, learners assume every subject name is neuter too. In fact each subject is an ordinary noun with its OWN gender: ✗ das Mathematik → die Mathematik (like most -ik nouns); ✗ das Geschichte → die Geschichte; ✗ die Sport → der Sport. The umbrella noun's gender tells you nothing about the subjects it names.
Build a school answer from four blocks
For a school answer: 1) name the subject with its gender; 2) anchor a fact to the timetable or a rule (man muss/darf (nicht) + infinitive at the end); 3) check every adjective before an ein-word noun (ein strenger Lehrer); 4) give an opinion with weil.
Word order: infinitive and weil-verb go last
Two checks catch most errors. With a modal verb, the infinitive goes to the clause end: man muss die Schuluniform tragen. After a subordinating conjunction (weil, dass), the finite verb goes to the clause end: ..., weil unsere Lehrerin geduldig ist.
Show tense range: present, Perfekt, a modal
Move beyond the present: today's routine in the Präsens, a past event in the Perfekt (gestern habe ich eine Klassenarbeit geschrieben), and a plan (modal/future: ich möchte mehr Wahlfächer haben). Check auxiliaries: haben for schreiben, sein for gehen.
Talking about school — subjects, the timetable, classroom items, rules and your opinion — is a staple Speaking topic conversation and Writing task in 0525. Every subject noun has its own fixed gender, and the modal-verb + opinion-with-weil pattern reused throughout the topic is fully within the section 1 grammar you already know.
