" Oh.. Then which universities are you opting?" Mark Harris cleared his mind and switched to the main topic.

" Harris University."

" And?" Mark raised his brows.

" My only option is Harris university.." Isabella spoke resolutely.

Mark Harris raised his eyebrows in amusement " Why so?"

Isabella cleared her throat and spoke in an excited voice " Because it's mathematics dept is the best. I can only enter the best one."

Isabella cupped her hands around her mouth as if she's telling a secret " Also, I heard that the old man of that dept is a very good professor. I love math.. So, I want to learn as much as possible..".

Mark Harris's brow twitched on hearing her words.. ' Girl, I am the old man you are talking about..' he sighed in his heart. He was curious about his future student now..

So, he looked at her " Get me a paper and pen.."

" Ah.." Isabella blanked out but she recovered immediately as she went near Ben and asked him for paper and a pencil. On hearing her request, Ben glared threateningly at his old man ' Be good to my sis.. or else..'.

Mark Harris choked while drinking water on seeing his grandson's partiality. He complained in his heart as he had no place to vent his sorrows.

Mark took the paper and wrote down a complex integration problem as his mood was sour at that time. He regretted his impulse after handing the paper to the girl before him. It is a very complex problem and it is almost impossible for an eighteen year old to solve it. So, he felt bad while looking at the young calf before him. What if he scared the hell out of her? Will she come to hate mathematics?

No way! He will absolutely not allow it.. It's very rare to come across someone who is interested in this subject. So, Mark Harris cleared his throat " Bella, I'm also a bit good at maths.. It's a difficult problem, so don't feel bad if you are not able to solve it. If you are able to write the limits of integration correctly, I will believe that you will get into Harris University."

' This man is clearly a monster in maths ah! How can he claim that he is only a bit good at it..' Isabella's lips twitched on seeing the problem and hearing the old man's humble words.

But, she felt excited on hearing his words. ' So, it's time to prove myself..' Isabella smirked and started to solve the problem without glancing at the old man before her.

Mark observed the girl's bright eyes when she is solving the problem. So, he looked at her in a trance. He came out of his daze on hearing her voice " Old man, take a look.." she raised her eyebrows with a mischievous smile on her face.

Mark Harris took the paper from her hand and he froze on seeing it. This girl solved the entire problem within 5 or 6 six minutes.. Also, she solved it step-by-step leaving no room for doubt in his heart.

He was pleasantly surprised and he smiled at her genuinely praising her

" Bella, you are a genius dear. It is their fortune to have a student like you."

Isabella grinned widely on hearing his words. Ben smiled when his grandfather praised his sister.. So, his impression on his old man improved by 0.00001%

Mark was completely satisfied by this girl. He thought for a while and looked at her seriously " Bella, I have two sons. I need not worry about the first one. But, my second son is a complete brat. I want you to tutor him in math."

Isabella looked at him with confusion " Old man, why can't you teach him yourself.."

Mark rolled his eyes at her " I'm busy and also you both are about the same age. So, he may listen to you."

Isabella thought for a while before answering " Old Mark, I can't teach him personally. But, I am a registered tutor in tutes.com. He can add me as his teacher there. It's just that I want to use my time to help as many as I can.."

Mark smiled on hearing her answer. This girl has all the qualifications to become a great professor. So, he did not force her " Alright, give me your id. I will pass it to him.."
