You can add 在 just after 会。

Duolingo has currently settled on "What will you be doing the day after tomorrow" to translate "后天你会做什么？", but the following translations better highlight some of the difference in nuance:

• 后天你做什么？—— What are you doing the day after tomorrow?

• 后天你会做什么？—— What will you do the day after tomorrow? / What are you going to do the day after tomorrow?

• 后天你会在做什么？—— What will you be doing the day after tomorrow? / What are you going to be doing the day after tomorrow?

Perhaps if you included the words "planning on" as the event is in the future.

Duolingo has currently settled on "What will you be doing" instead of "What are you doing". This is fine, as the former corresponds a bit better to the use of "会" in the Chinese.

However, it's also common to talk about future arrangements in the present tense (without using a phrase such as "planning on").

For the sentence with "planning on" you can say "你打算后天做什么？" or "后天你打算做什么？"

How about "What will you be doing the day after tomorrow?"

"What will you do the day after tomorrow?" is much better.

This is not testing my English but testing my Chinese. But I got all wrong because my English is wrong in grammar.
