But is the most common answer the correct one?

Both answers are right in terms of the purpose clauses ("so as not to be late for classes" or "to not be late for classes" (You have "to" in the clause twice, which would be fine if the second one was "too"--"to not be too late for classes"). In spoken American English you can usually put "not" inside the infinitive or before it "to not be late" vs. "not to be late." However, as a native American English speaker "in good time" sounds unusual to my ears. "I get up early" or "I get up with plenty of time" sound better to me. But it might be right for British English.

In Vindobonā habitō (non perfectō tempore nec voce passiva uti oportet.) . Haec urbs prope Flumen Dānuvium in mediō Eurōpae sita [urbs est nomen femininum], ac caput Austriae est. Hāc urbe multa antiqua aedificia praestantur, nec gesta memorābilium virorum et fēminarum [huius? nescio quid dicere velis hoc verbo. Potest "hic" aut "hoc in loco"?] ōblita [gesta sunt res plurimae neutrae] sunt.

This is a past contrary-to-fact subjunctive. It means something wise did not happen. If I had not drunk three vodkas, I would not feel sick now. It would have been wiser to stop after one. [The grammar of "would have been" makes it clear that I did not stop that night.]

Vocābula aliēna in linguā Latīnā antique In Linguā Latīnā nōn modo vocābula gentis Rōmanae (non refert ad civitatem sed populum qui loquitur Latīnā), sed etiam ex linguīs Indoeurōpaeīs et aliīs linguīs bene ūtilia sunt. Sī librōs histōriae legis (in III conjugationi. Si vis uti subjunctivi debet dicere "legas") , in hīs multa exempla ex Graecā scrībuntur (in III conjugationi). Graecia in tempore antiquō erat patria scientium. Et rēs lūdī et rēs librī bene vocābulīs Graecīs ūtuntur (verbum "uti" utitor casō ablātīvō. Cīvēs vel servī quī recitant, anagnōstēs dīcitur. Lūdus, in quō scientēs docentur, lȳceum vocātur. Sed nōn modo (pro? in?) scientiā, sed in mūsicā quoque lingua Graeca illūstris erat. Poetae, ars litterārium multum vocābulī Latīnae dabant. (Nescio quid dicere velis. Et poetae et ars litterāria multa vocabula Latīnae dabant?) Praetereā multōrum vocābulōrum (origo Etrusca?) credita est. Ad exemplum, tribūs antiquī Indoeurōpaeī significātiōnem fenestrae nesciēbant, sed Etrūscī eam in domī bene habēbant. Ergo vocābulum fenestram ex Etruscā vēnisse putātur. Sī de domū loquor, locus magnī momentī in hōc est larārium, fānum vel aedis lārum. Lārēs in religiōne Rōmānā deī domūs erant. [anglice: The Lars in Roman religion were the gods (nominative) of the house (genitive)] In rē deorum sunt vocābula de Etruscīs multa. Nōmina multōrum eōrum, sīcut Minerva et Iūnō, ex Etrūriā esse putātur.

Māne cotīdiē ea meā māchinā coffēae parātA est. Postquam statim bibere possum. Ego trīna aut quaterna pocilla bibō, quod fortasse nimis [multa] sunt, sed minuere nōlō. solum duo errores inveni-- oportet scribere "ea paratA est" et "nimis" satis est, non necesse est dicere "nimis multa" ut opinor. Macte virtute!
