100

The plane leaves at 8:00 AM tomorrow. 

CORRECT. We use the Present Simple to talk about official timetables and schedules.

100

She is always leaving her muddy shoes in the corridor!

CORRECT. Present Continuous combined with "always" is used to express annoyance or irritation about a repeated habit.

100

The train is about to leave. Hurry up!

CORRECT. The structure be about to indicates that something is going to happen imminently or in the very next moment.

100

I'm loving this movie, I'm going to watch it again tomorrow!

INCORRECT. "Love" is a stative verb and should not be used in the continuous form in standard grammar. The correct form is: "I love this movie".

100

If it will rain tomorrow, we will cancel the picnic.

INCORRECT. In a first conditional sentence, we must use the Present Simple after the conjunction "if": "If it rains".

200

I will meet my friend for coffee at 5 PM. I already bought the cake.

INCORRECT. It should be "I am meeting" or "I am going to meet". We use the Present Continuous or be going to for planned actions, arrangements, and clear intentions.

200

I think robots will do all the housework in 2050.

CORRECT. We use will for general predictions, beliefs, and opinions about the distant future.

200

By next year, they will build a new bridge over the river.

INCORRECT. The time marker "by next year" (meaning no later than next year) requires the Future Perfect: "will have built".

200

Next week we are going to celebrate our 10th anniversary; we’ve already booked the restaurant.

CORRECT. The sentence correctly uses be going to to express a firm intention (Present Continuous would also work perfectly here since a booking has been made).

200

200 points: I will call you as soon as I will arrive at the station.

INCORRECT. After time expressions like "as soon as", we use the Present Simple to refer to the future, not will: "as soon as I arrive".

300

Look at those black clouds! It is going to rain.

CORRECT. We use be going to for making predictions based on present, visible evidence.

300

At noon tomorrow, I will have been sitting in the office.

INCORRECT (or highly unnatural). At a specific, single point in time ("at noon"), we focus on an action in progress. Therefore, the Future Continuous is required: "I will be sitting".

300

Will you be passing by the post office this afternoon? Could you post this letter for me?

CORRECT. This is an advanced use of the Future Continuous to make polite, neutral inquiries about someone's existing plans when you want to ask for a favor along the way.

300

At 9 PM, I will be watching the match, but by 11 PM, I will have watched it.

CORRECT. A flawless combination: at 9:00 PM the match will be in progress (Future Continuous), and by 11:00 PM it will be a completed result (Future Perfect).

300

Unless you will finish your project, you won't get a bonus.

INCORRECT. The word "unless" means "if not" and acts as a conditional conjunction. It must be followed by the Present Simple instead of will: "Unless you finish your project...".

400

Don't phone me between 8 and 9 PM tonight because I will watch a movie.

INCORRECT. Because the action will be in progress during that specific time frame, you must use the Future Continuous: "I will be watching".

400

Are you going to open the door, please?

 INCORRECT. For polite requests or asking someone if they are willing to do something, we use will: "Will you open...".

400

I will have been working here for 5 years tomorrow.

CORRECT. The Future Perfect Continuous is used correctly here to emphasize the duration of an ongoing action up to a specific point in the future.

400

I will have written three emails by noon, but I will have been writing them all morning.

CORRECT. A great contrast: the first part focuses on the result and quantity (Future Perfect), while the second part highlights the ongoing process and duration (Future Perfect Continuous).

400

This time tomorrow, I’ll be sitting on a beach in Mallorca.

CORRECT. Classic use of the Future Continuous to describe an action that will be in progress at a specific, defined point in the future.

500

By the end of this month, I will have finished this book.

CORRECT. We use the Future Perfect for an action that will be completed BEFORE a specific point of time in the future.

500

The timetables say that our plane will land at 4 PM tomorrow.

INCORRECT. Since the statement refers directly to an official scheduled timetable ("the timetables say"), you must use the Present Simple: "our plane lands at 4 PM".

500

I will have been typing this report for three hours by the time you arrive.

CORRECT. A complex Future Perfect Continuous structure that properly highlights the duration and continuity of an ongoing process before another action happens in the future.

500

This time next year, I will study at university.

INCORRECT. It should be "I will be studying" (Future Continuous is required for an action that will be in progress at a specific moment in the future).

500

I'm going to start my driving test at 10:00 tomorrow, so don't call me then.

INCORRECT. Stylistically unnatural given the request not to contact them. Because you are telling someone not to call because you will be busy in the middle of an action, the Future Continuous is preferred: "I will be taking/doing my driving test".
