The correct answer is "had" because it is in the past subjunctive form of the verb "have", which is used in conjunction with "wish" to express a hypothetical or unreal action or condition in the past. In this sentence, the speaker is expressing regret or disappointment about not having more time to prepare for the presentation, but this is a hypothetical or unreal situation because the time has already passed.
Option "have" is incorrect because it is in the present form of the verb, which is not appropriate to express a hypothetical or unreal action in the past.
Option "would have" is incorrect because it is in the past conditional form of the verb, which is used to express a hypothetical or unreal action in the future.
Option "will have" is incorrect because it is in the future form of the verb, which is not appropriate to express a hypothetical or unreal action in the past.
Subjunctive mood
The subjunctive mood is the verb form English uses for hypothetical, counterfactual, or formal-recommendation contexts. The two main patterns are: the present subjunctive in that-clauses after verbs of recommendation/insistence (I suggest that he go, It's essential that she be informed), and the past subjunctive were in counterfactual conditionals (If I were you).
Most subjunctive forms in modern English look identical to the indicative — the visible signs are the missing third-person -s (he go, not he goes) and were with first/third-person singular (if I were). Easy to miss; a strong marker of careful, formal English when used.
Conditional sentence
A conditional sentence describes one situation as depending on another. It pairs a condition clause (usually starting with if) with a consequence clause: If it rains, we'll stay in. The condition can refer to general truths, real future possibilities, hypothetical present situations, or unreal past situations — and each type uses a specific tense pattern.
English teaching groups these into zero, first, second, third, and mixed conditionals. Mastering them lets you talk about plans, regrets, hypotheticals, and warnings — territory you can't reach with simple present and past tenses alone.
C1 | Advanced
C1 is the advanced level in the CEFR framework, sitting between B2 and C2. At C1 you stop translating in your head and start thinking in English — handling specialised articles outside your field, picking up implicit meaning, and writing structured arguments on complex topics.
Grammatically, C1 means natural use of inversion (Rarely have I seen…), mixed and advanced conditionals, subjunctive forms in formal contexts, and cleft sentences for emphasis. Most university programmes for non-native speakers and many professional certifications set C1 as their entry standard.
C2 | Proficiency
C2 is the highest level in the CEFR framework — the proficiency stage, where your English is nearly indistinguishable from a well-educated native speaker's. C2 users handle irony, understatement, and idiomatic range across any register, and they reformulate ideas under pressure without losing fluency.
C2 is less about learning new grammar and more about mastering the flexible, context-sensitive use of everything you already know. Most learners never reach C2 — and most don't need to. Knowing the level helps you set realistic goals: B2 or C1 is plenty for almost any practical purpose.
Difficulty: Hard
The Hard difficulty tag marks questions and challenges aimed at upper-intermediate to advanced learners — typically B2 and above. Expect interacting rules, edge cases, distractors that look right at first glance, and contexts where the surface meaning and the grammatical answer don't match.
Filter by Hard when you're past the basics and want material that genuinely tests your understanding. These questions catch the gaps your textbook didn't — register-sensitive choices, exception cases, mixed conditionals, the difference between would have been and had been.
