Mock test plays an important role in your preparation phase. So having a good mock test series can boost your preparation to the next level. The online MOCK TEST's you can buy from institutes such as-

• BYJU'S
• AGLASEM
• TOP Rankers

can be really good, otherwise you can always prefer the offline mock series near your home.
