If this is about leveling then you can do it the hard way or the easy way.
The hard way:Each attribute governs three skills. At level up you definitely want to raise it by five. So every level you want to raise each of the three skills four points each in order to earn your +5 attribute. You would need to keep track of the skills you raise with a notepad and pencil because Oblivion may crash if you alt tab to the desktop to use Windows Notepad. So, for example, you would raise Blade, Blunt, and Hand to Hand four points each to gain your +5 in Strength.
The easy way:Use a leveling mod. I recommend Realistic Leveling by abo.
