Is it correct using अब later? राज नेहा के साथ अब काम करेगा
They do not accept when i write : राज नेहा के साथ अब काम करेगा
Is this sentence really wrong ?
Pleas duo correct it . There are several examples like this in this course
Yes, this is also correct. You can move अब to almost every position within the sentence.
When we click the word "अब" it sounds like the English word Ab like in your body....
Agreed, it's weird. Is that correct?
No, it's wrong. It's pronounced exactly how it's written in Devanagari.
I have marked as "should be correct" the alternate position of अब multiple times. I hope it's fixed soon
The position of 'now' in the given English is absolutely fine, and - as a native speaker - exactly what I entered.
What's the difference between karenga and karega here
करेंगे (karenge, not ~ga) is the masculine plural (incl. honourific as always), while करेगा (karega) is the masculine (2nd/3rd person) singular.
तू करेगा tu karega; आप/वे करेंगे aap/ve karenge.
