Let $$ n $$ represent the total number of problems on the test.

1. Since the student answered $$86$$ problems correctly and received a $$98\%$$ score, we have:
   $$
   \frac{86}{n} \times 100 = 98
   $$

2. Dividing both sides by $$100$$ gives:
   $$
   \frac{86}{n} = 0.98
   $$

3. Solve for $$ n $$ by isolating it:
   $$
   n = \frac{86}{0.98}
   $$

4. Calculate the value of $$ n $$:
   $$
   n \approx 87.7551
   $$

5. Rounding to the nearest whole number:
   $$
   n = 88
   $$

Thus, there were $$88$$ problems on the test.
There were 88 problems on the test.
