Ravel is only 2-3 years older than Rias (she did attend Kuoh Academy as a 1st year so she's probably the same age as Koneko like 15 or 16) so she would have to be 1-2 year younger than Issei and 2-3 years youger than Rias(I checked the wiki page and they don't list her specific age but you can assume it's around Koneko's age). We can tell Riser is ALOT older, the evidence being he was able to participate in alot of Rating Games before the start of DxD and he even states "only older and experienced devils are allowed to participate). From this I can tell that Riser is either in his early 20s or late 20s but I don't think he's the same age as Rias.

So if Rias is 10 Riser would most likely be in his early/late teens which makes alot more sense that Ravel be there. Besides, considering Riser's personality at the beginning of DxD I doubt he would want to go to a Rating Game school.

The problem in this show is that Lord Gremory looks the same age as Riser but you know Lord Gremory is hundreds of years older. You can't tell anybody unless mentioned actual age.
