As far as I know there is no GetPlayerSkillLevel, so what I would do is create a variable that'll keep the skill level for example.

pawn Код:

new SAWNOFF_SKILL[MAX_PLAYERS]; //(don't use this, implement it how you want it).

public OnPlayerConnect(playerid)
{
    //load the skill variable and store it inside 'SAWNOFF_SKILL[playerid]'
}

//then if you want to increase his skill level by one you simply do;

SAWNOFF_SKILL[playerid]++;
SetPlayerSkillLevel(playerid, WEAPONSKILL_SAWNOFF_SHOTGUN, SAWNOFF_SKILL[playerid]);

//if you want to decrease his skill level you do;

SAWNOFF_SKILL[playerid]--;
SetPlayerSkillLevel(playerid, WEAPONSKILL_SAWNOFF_SHOTGUN, SAWNOFF_SKILL[playerid]);

//when you want to save it you just store SAWNOFF_SKILL[playerid] in the players file

You can use any saving include (or plugin) like y_ini, mysql, sqlite
