    What do your negatives look like? are they quite dark?
    What aperture is the lens set at?
    Are you using f11-f16?
    I would forget grade 1 and 2 for now.I usually do test strips in 5-7 second stages depending on the negative and format.Sometimes up to 35 seconds in total.

    If the paper is coming out white or too light, then you are under-exposing and you need to expose for longer.
    If it's coming out too dark then you need to expose for less time.

    If you are exposing with an enlarger then the lens should have an aperture setting ring with numbers like 5.6, 8, 11, 22 etc on it. Setting it to f/11 would be a good starting point.

    Also perhaps you could describe what paper you are using and how you are developing it (what chemicals, in what order, for how long) in case there is a problem there.

    Yes the enlarger lens, what aperture are you using for your test strip?
    For 35mm i usually test strip print at 5 second stages using f8. 7 seconds if the print a little dark
    ( overexposed) 7 seconds x 5 = 35 seconds.
    Have a look at the links below

    what paper are you using?
    Are you exposing the emulsion side of the paper?

    By the sounds of it, you could do with spending an hour or so with somebody who can demonstrate the basics of darkroom work - If we knew where you were, someone may offer to show you the ropes.
