Creating an Array!

[Cinnamonom]

Hey all.
Forgive me if this seems noobie, but I am completely new to coding in vb.net
I'm trying to make an array that sorts Students into certain areas, like the mark they get(A+, A, B etc), whether they get an award or not and stuff like that.
Problem is, I've been thinking about how to code this for a few days now and I'm completely stumped.
Any help would be appreciated, thank you in advance.

Grouping the data is not especially difficult, but we'd need to know more about what form the data is in to begin with.

Sorry about my noobiness, but what do you mean?
Heres what I got;

A teacher keeps records of his seven students’ performance over three assessment tasks: a project, a practical test and an exam. All assessments are graded as a percentage. The marks are recorded with the students’ names: Alex, Beth, Colin, Darcy and Egbert. He does not want to have to re-enter the students’ data every time he runs the program.
The teacher gives you the data for the class and wants you to write a program to calculate:
- Each student’s average grade as a percentage over the 3 tasks.
- The average class mark for each task.
- The highest and lowest exam marks, and who achieved them.
- Which students get an achievement award. This is given to students who get over 75% for the practical test and 80% or more in either the project or the exam.
- A semester letter grade. This is calculated as follows:
Semester
average % Grade
91-100 A+
80-90 A
61-79 B
51-60 C
46-50 D
31-45 E
0-30 UG


As far as any other data goes, no marks were given to me, so I'm guessing the teacher would have to input them himself, the only other data given are the students names.


Edit:
I know how to code a multidimensional array, or rather, I found a tutorial helping me with it.
But that's about all I know that I'll need to do this.
Edit2:
I also found a tutorial on how to be able to add data to the array "on the fly" instead of having a set amount.
I also want to combine the two together, which I have no idea to do either.
