function admit = eligible(v,q);
avperc = mean([v,q]);
if avperc>= 92 && (v>88&&q>88)
admit = true;
else admit = false;
end

Nowhere in your function do you define the variable admit the function returns as its output. You haven't shown the full text of the homework question but I suspect it tells you to have your function return true or false instead of printing the text "true" or "false". To do that assign a value to the variable.
admit = true;
admit = false;

q and v are numeric values. When you use the && operator between them, admit=q&&v is defined as
if q ~= 0
if v ~= 0
admit = true;
else
admit = false;
end
else
admit = false;
end
However, the assignment makes no mention of testing for zero or not.
In particular when you get to your else branch, admit=~q&&v then that would be true if q was 0 and v was non-zero, leading you to admit someone with a score of 0 for q when the assignment would require that they be rejected because 0>88 is false.

After enough struggle I am wondering who can help me understand why I'm returning errors from this program. Thanks
function admit = eligible(v,q)
avperc = mean([v,q]);
if avperc>= 92 && (v&&q>88)
admit = true;
else admit = false;
end
end

One closes the if, the other closes the program.
While using an end to close the program is optional, it is recommended that you do. If functions are explicitly closed with an end, you can use nested functions and you can define local functions in a script.
