Mistakes in the Use of Prepositions
1 Bad (i) Bad at The use of the preposition in in the first sentence is wrong. It should be replaced with at. • The boy is bad in Mathematics. ✘ • The boy is bad at Mathematics. ✔ (ii) Worse at, Worst at Similarly, the use of in for the comparative and the superlative of bad (worse and worst) is also wrong. • The boy’s brother is worse in Mathematics. ✘ • His friend is the worst in Mathematics. ✘
The correct sentences are: • The boy’s brother is worse at Mathematics. • His friend is the worst at Mathematics.

2 Excel (i) Excel at (an activity) According to English Prepositional Idioms by Frederick T. Wood, for being extremely good at an activity, excel in may be used but excel at is more common. • This artist excels in painting birds. ✘ • This artist excels at painting birds. ✔ (ii) Excel in (an attribute or quality) According to the same source, the use of the preposition at is not appropriate when we use excel for qualities or attributes. • She excels at intelligence. ✘ • My brother excels at foreign languages. ✘
It would be more appropriate to write the sentences as: • She excels in intelligence. ✔ • My brother excels in foreign languages. ✔ 1
