Scholarship / I was born in a beautiful, landlocked country - Botswana. SELF INTRODUCTION FOR THE KGSP [10]

"... i played among the boys ""which"" developed my love for sports."
Correction:
Change "which" to "who", because word "the boys" is person.

"...more especially from a tender age even ..."

Correction:
Change "more especially from" to "more special than", because more is bonded to than, and especially is adverb but there is no adjective or verb to explain, so word special is suitable.

"so this the reason i want study in Korea"
Correction:
Between verb "want" and "study", there is a preposition "to".
