A CASE statement should work, if you are willing to hard-code the list of expressions.
SELECT username,
sum(case when avg between 76 and 85 then 1 else 0 end) as "76 to 85",
sum(case when avg between 86 and 95 then 1 else 0 end) as "86 to 95",
sum(case when avg > 95 then 1 else 0 end) as ">95"
FROM yourtable
GROUP BY username
SELECT username,
sum(case when avg between 76 and 85 then 1 else 0 end) as "76 to 85",
sum(case when avg between 86 and 95 then 1 else 0 end) as "86 to 95",
sum(case when avg > 95 then 1 else 0 end) as ">95"
FROM yourtable
GROUP BY username
