Hi precious, Both of these would be understood, but only one is correct. You have to say "on his original course". Using "in" is wrong.

Hi precious, Both of these would be understood, but only one is correct.
You have to say "on his original course".
Using "in" is wrong.
Unfortunately, there are no simple rules for choosing between "in" and "on" and you have to learn each case individually.
For example, you would say: "on his original course" but "in his original direction" "he got on a train" but "he got in a car" "on average, he earns £50" but "in total, he earns £50" There are no simple rules to follow.
