Dear Heskey,
Get stronger in compound movements - Bench, Deadlift, Squat, Chin-ups/Pull-Ups, Overheadpress and Rowing (You can do dumbell-rows, Bend-over-barbell-row or preferably a chest-supported rowing machine, where your lower back/body doesn't need to work so you can concentrate on the rowing movement only.
Do 5-8 Reps at MAX in compound movement, higher rep ranges are for isolation/assistance exercises. If you are a beginner, focus on compound movements, just do very little isolation work.
If you're capable of doing 10-12 full range of motion and slow chin-ups at ~ 90 kg bodyweight with 15 kg additional weight, believe me, you never need a single curl to have a big and strong bicep.
Don't train some stupid split if you're a beginner - do 3 full body workouts per week until you got intermediate strenght data, something like around 85 kg Bench, 115-125 kg squat and 130 Deadlift (as working weights, not 1 rep max.) It's counterproductive to split your training if you're not an intermediate lifter.
I got middle to end Intermediate/beginning of advanced strenght standards (depending on the specific exercise) and I am still doing an alternating full body workout 3-4 times a week, or a split with 2 different workouts 4 times a week (upper/lower body).
For strenght standards I recommend this
http://www.strengthstandards.co/#/ . There are different formulas on different sites, so individual strenght standards may differ a little, but thats not important.
(EDIT: You can of course do higher reps ranges for any compound movements, but as a beginner, its not necessary, or lets say, it's useless because the weight you move with higher reps, say 10-12, is way to low. So do 5-8 Reps)
Have fun!
