Martin speaks highly of his grades to the principal.
Martin resorts to begging Mr. Muzawazi to let him in.
Mr. Muzawazi gives Martin time to pay the fees.
Martin Ganda has received all As on the A-Level exams at his previous school, and he hopes to attend Marist Brothers School. Since this school is for the smartest kids in Africa, Martin is required to pay a large fee to enter, however, he can not afford it and hopes that having his high grades will make Mr. Muzawazi let him in. He talks to him in his office and feels "a big ball of emotion" as nerves overtake him.
Martin can not get Mr. Muzawazi to budge on letting him into the school for free, so he begins to beg for it. He does not wish to do so, but it is his last chance. He tells about how his parents are barely literate and begins to think and miss them. It is unknown whether Martin's tears made Mr. Muzawazi think, but he begins to consider what Martin wants.
This scene is significant because it shows how much Martin's life has improved from where he began. He is now able to attend a prestigious school which could mean American colleges in the future. Martin expresses happy emotions as Mr. Muzawazi extends the date for him to pay. Although this might not mean problem solved for some, it gives Martin time to contact Caitlin for the money to pay fees.
