"I will be thinking about it tomorrow."

Translation: Będę o tym myślała jutro.

[Euhan1]

I happened to write the subjective pronoun and it didn't work. Is it actually wrong to say "ja będę..."?

[Jellei]

That's an oversight. Using "ja" can very often be a bit clumsy, but it's definitely not wrong. Added now.

I hear Poles say "Będę jutro (czasownik) coś..." Why is placing the time before the verb wrong?

[Jellei]

It's okay, it's accepted, but because of some mistake the male forms (myślał) were missing from the potential answers, added them.

Pomysle o tym jutro. Moze byc?

[Jellei]

I think that's rather a translation of "I will think about it tomorrow" and not of "I will be thinking" which puts emphasis on the process.

What is the difference between myśleć o czymś and myśleć nad czymś?

[Jellei]

I feel that "myśleć nad czymś" is about some particular... problem? Something that you can solve, give an answer. "myśleć o czymś" is the basic variant.
